Courage Over Comfort: A Woman Leader’s Guide to Navigating the Fear Zone

By Stacey St. John, Certified Stagnation Assassin Consultant | Author of LIVE BIG

The Shoes That Changed My Life

Have you ever watched a woman glide in 4.5-inch stilettos and thought, “Wow, walking in those looks so easy!” Yeah, me neither.

Let me tell you about the shoes that changed my life.

My barbershop quartet was gearing up for a big singing competition, and we had this fierce, head-turning costume, candy apple red tops paired with sleek, leather-look Spanx. Sass meets class. But we were missing one thing: shoes. They had to sparkle, and they had to be the exact shade of red.

After what felt like hours of searching online, I found THE shoe. An eye-catching band of rhinestones that practically screamed, “Look at me!” The exact red I’d been hunting for.

The heel? 4.5 inches tall.

I’d worn plenty of heels in my life, but nothing that high. I thought, “Maybe I should keep looking.” But no other shoe came close. So naturally, I ordered them anyway.

When they arrived, I slipped them on and instantly thought, “Oh no, there’s no way I can walk on stage in these, let alone stand and sing!” I felt like Bambi on ice. My first instinct? “I’ve got to send these back.”

But something inside me said, “Try again.”

The next day, I strapped them back on, still convinced I needed a different pair. But that little voice whispered, “Stacey, these are the shoes. Keep going.”

So I kept practicing. Walking around the house, slowly but surely. The wobble disappeared. After a few weeks, I could finally walk and look straight ahead instead of staring at the floor. Then came the real test: standing and singing in them. I was focused on not tipping over rather than singing, I sounded pretty awful. But I kept at it, practicing over and over until I could stand tall, walk confidently, and sing my heart out.

Those red stilettos weren’t just shoes. They were a lesson.

I didn’t just master walking in those heels, I discovered an inner strength and tenacity that had been lying dormant. There was a voice in my head telling me to give up, to take the easy way out. But I knew better. I knew I had to keep going, ignore those self-doubts, and push through what I call the Fear Zone.

The 4 Zones Every Leader Must Navigate

When you’re ready to crush your goals, the first thing you’ll encounter is your comfort zone. Stepping outside of it is hard, and the moment you do, you’ll find yourself in the Fear Zone. That’s when the voice inside starts whispering, “I’m not cut out for this. This is too much work. Why does everything have to be so hard?”

Suddenly, you’re tempted to retreat back to safety.

But here’s the truth about that temptation: it’s actually a sign that you’re on the path to growth.

The four zones every leader passes through are:

The Comfort Zone. Familiar. Safe. Easy. Nothing new grows here.

The Fear Zone. That uncomfortable space where everything feels shaky. Fear and uncertainty try to pull you back. This is where most people quit.

The Learning Zone. You’ve pushed through the fear. You’re acquiring new skills, gaining confidence, and building momentum.

The BIG Zone. You’re consistently operating at your full potential and living a life filled with joy and purpose.

The magic, the transformation, happens in the Fear Zone. Not the Comfort Zone, not the BIG Zone. The Fear Zone is where your inner peace and strength wake up, and where real growth begins.

This isn’t just motivational talk. Leadership scholars at IMD Business School have found that one of the greatest barriers to leadership development is that people select programs that reinforce their existing comfort zones rather than challenge their underlying assumptions about what effective leadership looks like. According to research by Hannes Leroy and colleagues published by IMD in 2024, leaders hold strong personal ideologies about leadership, and these ideologies can become cages that prevent genuine growth. Real development, they argue, requires deliberately choosing discomfort over familiarity.

In other words, the Fear Zone isn’t a bug in the growth process. It’s the feature.

The Neuroscience of Fear: Why Your Brain Fights Your Goals

Inside your brain is a central control room called the amygdala, and inside it is your subconscious mind dressed up as a security guard on constant high alert. Its sole mission? To keep you safe. It scans your environment, both physical and mental, looking for potential threats.

A suspicious shadow on the street? “Danger!” A looming deadline? “Danger!” A creepy, 8-legged hairy insect? “RED ALERT!”

Here’s the critical part: your brain can’t tell the difference between a bear in the woods and your imaginary fear of public speaking. It simply throws up the stop sign, triggering the release of stress hormones like adrenaline and cortisol. These hormones prepare you for fight or flight.

This mechanism served us well in caveman days. But in our modern world, where the biggest threat during your day might be a missed bus, this constant state of high alert can be exhausting. And it can hold you back from the ability to LIVE BIG.

Decades of neuroscience research have confirmed the amygdala’s central role in this process. A landmark review published in Biological Psychiatry through the National Institutes of Health (PMC) demonstrated that the amygdala functions as a core hub in the brain’s fear circuitry. The research, led by scientists at Emory University, showed that chronic stress can cause the amygdala to become hyperexcitable, essentially putting it on a permanent hair-trigger. But here’s what’s fascinating for leaders: the research also found that engaging active coping strategies, rather than remaining in a passive “frozen” state, can decrease stress activation and improve psychological function.

In plain language? Sitting in fear makes fear worse. Taking action, even imperfect action, helps rewire the brain’s response.

This connects directly to one of the most exciting discoveries in modern neuroscience: neuroplasticity. A 2025 review article published in the journal Brain Research confirmed that neuroplasticity, the brain’s capacity to reorganize itself by forming new neural connections, continues throughout the entire lifespan. It is not limited to childhood. The review examined synaptic plasticity, structural remodeling, and neurogenesis, concluding that the brain remains remarkably adaptable in response to new experiences, behavioral interventions, and even deliberate mindset shifts.

What does this mean for you as a leader? It means every time you choose courage over comfort, you are literally building new neural pathways. You are constructing the architecture of a bolder brain.

Additional research published in Frontiers in Aging Neuroscience (2024) found that learning-induced neuroplastic changes can be observed in healthy adults engaged in cognitively demanding activities. In one famous longitudinal study of London taxi drivers, the acquisition of complex spatial knowledge was associated with measurable increases in gray matter in the hippocampus. Mental rehearsal alone was shown to induce neuroplastic changes in the brain.

The implication is powerful: you don’t have to wait until you’ve conquered your fear to start building a courageous brain. Visualization, rehearsal, and deliberate practice begin reshaping your neural architecture from day one. Your brain changes in response to what you do. Practice fear, and you wire yourself for more fear. Practice courage, and you wire yourself for more courage.

The Double Fear Zone for Women Leaders

For women leaders specifically, the Fear Zone has an extra layer.

McKinsey’s landmark Women in the Workplace 2024 report, the 10th-anniversary edition of the largest and most comprehensive study on the state of women in corporate America, revealed data that should stop every leader in their tracks. For every 100 men promoted to manager, only 81 women achieved the same milestone. For Black women, that number dropped to a devastating 54 for every 100 men. The report called this the “broken rung,” the critical first step up to management that, when missed, creates a cascading gap throughout the entire leadership pipeline.

The consequences ripple upward. Women hold just 29% of C-suite positions, up from 17% in 2015, but at the current pace, full parity for white women is projected to take 22 years, and more than twice that for women of color. The McKinsey authors, including Kweilin Ellingrud and Lareina Yee, went on to publish The Broken Rung: When the Career Ladder Breaks for Women—and How They Can Succeed in Spite of It through Harvard Business Review Press in 2025, arguing that waiting for companies to change is not a strategy and that women must take individual action to build their own “experience capital.”

But the broken rung only tells part of the story. Harvard Business Review’s research on women and the “vision thing” uncovered another critical barrier. In a study of thousands of 360-degree assessments collected by INSEAD’s executive education program, researchers Herminia Ibarra and Otilia Obodaru found that women outscored men in most leadership dimensions measured, with one significant exception: envisioning, the ability to recognize new opportunities and develop new strategic directions. But the researchers offered three explanations that suggest this gap is not about ability at all.

First, women may do just as much visioning as men but go about it in a more collaborative, less directive way, which doesn’t fit the prevailing mental model of a “visionary.” Second, women who have built careers on detail-focused execution may hesitate to stray from concrete facts into unprovable assertions about the future. Third, many women have seen bluster passed off as vision and may dismiss the importance of selling grand narratives.

The gap isn’t ability. It’s permission. Women are conditioned to play safe, not to envision boldly.

This means women face a double fear zone: internal resistance from the brain’s safety mechanisms PLUS external consequences for bold behavior. Men who take big swings are “visionary leaders.” Women who take big swings can be labeled “aggressive” or “emotional.”

A 2024 study published in Harvard Business Review by researchers Ivona Hideg and Winny Shen provided striking evidence of this double standard in action. Studying 137 leader-report pairs in Europe during the early stages of the COVID-19 pandemic, they found that women leaders reported higher anxiety levels than their male counterparts, yet did not translate those emotions into abusive leadership behaviors. Male leaders, by contrast, exhibited more hostile supervision when anxious. Women typically continued engaging in family-supportive and compassionate leadership behaviors regardless of their emotional state.

The researchers concluded that the stereotype of women being “too emotional” to lead effectively is not just wrong, it’s backward. Women demonstrated superior emotional regulation under pressure, but the very stereotype continues to undermine their perceived leadership capability.

That makes courage even more necessary, and yes, even more costly. Which is why it must be practiced deliberately, not left to chance.

The Broken Rung and What It Really Costs

Let’s linger on the broken rung for a moment, because its implications extend far beyond individual careers.

The McKinsey Women in the Workplace 2025 report showed that only 93 women were promoted to manager-level roles for every 100 men. For women of color, the disparity was even wider, with only 74 women of color promoted for every 100 men. And for the first time, the report documented a notable ambition gap: 80% of women wanted to be promoted to the next level, compared to 86% of men. But, critically, this gap disappears when women receive the same level of career support that men receive.

The problem isn’t that women lack ambition. The problem is that the system hasn’t earned their ambition. When women repeatedly hit barriers, when they’re interrupted more in meetings, when their ideas receive less credit, when they’re held to higher standards for promotion, their rational response is to recalibrate expectations. It’s not a lack of fire. It’s a fire that’s been dampened by systemic headwinds.

This is why individual courage matters so much. Not because it’s women’s responsibility to fix a broken system, but because in the absence of systemic change, individual agency becomes a survival skill. And when enough women practice that agency visibly, it begins to reshape the system itself.

Research by the Potential Project, published in partnership with Harvard Business Review and based on a multi-year study across approximately 5,000 companies in nearly 100 countries, found that 55% of women leaders were ranked by their followers as being both wise (displaying the courage to do what needs to be done) and compassionate, compared to only 27% of men. The study also found that employees who work for a wise and compassionate leader experience 86% higher job satisfaction, and that women leaders save their organizations an estimated $1.43 million for every 1,000 employees through higher engagement and lower disengagement. When women leaders leave, the losses multiply, not just for gender parity, but for organizational performance across the board.

The data makes the case plainly: the world doesn’t just need more women in leadership. It needs the specific qualities that women leaders disproportionately bring, wisdom, compassion, and the courage to lead through complexity rather than around it.

How to Push Through the Fear Zone

So how do we actually push through?

(1) Commit to it. Decide, right now, that you will not let fear make your decisions for you. This isn’t about eliminating fear, it’s about refusing to let it drive.

(2) Be the person who pushes through fear. Yes, you can fake it until you make it. This is Commit-Be-Do in action. Commit to being courageous. Be the person who faces fear head-on. Do what a courageous person does.

(3) Do the things a courageous person does. Take the meeting. Make the pitch. Have the hard conversation. Apply for the role. Launch the business.

Commit. Be. Do.

This framework, which I detail in my book LIVE BIG, flips the common “Have-Do-Be” mentality on its head. Most people believe they need to have a certain level of success before they can do the work and finally be the person they want to become. Commit-Be-Do reverses the sequence. You commit to the outcome, you step into the identity of the person who achieves it, and then you take the aligned actions. The results follow.

The Power of Practice

While Commit-Be-Do is surprisingly simple, it requires practice. Malcolm Gladwell, in his book Outliers, argues that mastering a skill takes 10,000 hours. While that might sound daunting, Josh Kaufman, author of The Personal MBA, offers a more attainable approach, you can go from novice to competent in just 20 hours of focused effort. That’s 45 minutes a day for a month.

The common thread? Putting in the work. Understanding something and actually doing it are two entirely different things.

Think about parallel parking. You could recite the textbook method flawlessly, yet still find yourself in a sweaty battle with a curb downtown. Just like parallel parking becomes second nature after countless attempts, any skill requires transforming theory into instinctive action.

This is where the neuroscience of habit formation becomes incredibly relevant. Your brain operates on a habit loop consisting of three components: a cue (or trigger), a routine (the behavior), and a reward (the benefit). As I explain in LIVE BIG, when you understand this loop, you gain the power to disrupt negative patterns and deliberately install new ones. Every time you choose courage over retreat, you’re not just making a decision. You’re laying down neural pavement. The more you travel that road, the wider and stronger it becomes.

How do we incorporate practicing courage as a regular part of our journey?

Embrace challenges. Accept the initial wobbliness and expected stumbles. Celebrate the effort and risk-taking, not instant mastery.

Prioritize your efforts. Trying to master too many things at once is a recipe for burnout. Zero in on one or two high-impact areas. Nail those, celebrate, then move on.

Dedicate time. Block time in your schedule to focus on skill-building. Most people just “wing it,” making slow, aimless progress. When you actually carve out time, you start making real strides daily.

Fear-Busting Tools from the LIVE BIG Toolkit

Here are my go-to techniques for busting through fear in real time:

Power Breaths

Take six deep breaths. With each breath, say: “I breathe in courage; I breathe out fear.” As you breathe in, hold it for a second, savoring the feeling. Then slowly exhale through pursed lips, like blowing out a birthday candle. This tells your brain what you’re taking in and what you’re letting go of, countering the stress reaction.

This isn’t woo-woo. Research published through the National Institutes of Health (PMC) has shown that mindfulness and deliberate breathing practices can measurably reduce amygdala reactivity to emotional stimuli. In a study of both long-term meditators and participants in an 8-week Mindfulness-Based Stress Reduction course, meditation training was associated with altered neural circuitry of automatic emotion regulation, specifically through modulating connectivity between the ventromedial prefrontal cortex and the amygdala. In plain English: deliberate breathing literally changes how your brain processes fear signals.

The Experience Coin

Everything has two sides, positive and negative. You get to choose how you see it. When you face a scary situation, picture a coin in your palm. One side: “Positive + Empowering.” The other: “Negative + Disempowering.” Ask yourself: “What’s the hidden gem in this challenge? How can I use this to become stronger?” Choose the empowering side.

This isn’t just a mindset trick. It’s a cognitive reframing technique supported by decades of psychological research. The perspective you assign to an experience determines how you feel about it, which then affects your actions. When you consistently choose empowering perspectives, you create a positive feedback loop that compounds over time.

Awareness → Choice → Intention

This is the three-step formula for taking back control.

First, become aware of what you’re feeling. Mindfulness research consistently shows that simply naming an emotion reduces its intensity. When you label fear as “fear” rather than being consumed by it, you activate the prefrontal cortex, which moderates the amygdala’s alarm response.

Then recognize that you have a choice, stick with the familiar or step into the unknown.

Finally, set an intention for how you want to think, feel, and act. Intention transforms random choices into deliberate steps toward your outcomes. It’s the difference between drifting through life and actively navigating toward your dreams.

The Self-Fulfilling Prophecy of Courage (and Fear)

Research on self-fulfilling prophecies, a concept first described by sociologist Robert K. Merton in 1948, shows that when we hold strong beliefs about a future outcome, we unconsciously behave in ways that make that outcome more likely.

The seminal research by Rosenthal and Jacobson (1968), known as the Pygmalion effect, demonstrated this powerfully in educational settings. When teachers were told that randomly selected students showed “unusual potential for intellectual growth,” those students actually performed significantly better on subsequent IQ tests, not because they were more capable, but because teachers’ expectations changed their behavior toward those students. They gave more time, more specific feedback, and more approval to the students they believed would excel.

The Ohio State University Fisher College of Business has documented how this same phenomenon operates in organizational settings. According to their analysis, leaders who hold high expectations toward subordinates’ performance outcomes exhibit more leadership behaviors aimed at facilitating and motivating employees, and provide consistently more positive feedback. As a result, employees’ self-expectations and self-efficacy increase, they exert more effort, and they achieve the high expectations set for them. The cycle becomes self-sustaining.

The implication for navigating the Fear Zone is profound: fear-based beliefs create fear-based results. Courage-based beliefs create courage-based results.

If you believe you’ll fail, you unconsciously withdraw effort, avoid risk, and sabotage your own performance. If you believe you’re capable of growth, you lean in, take the meeting, make the pitch, and your behavior generates the very outcomes you expected.

The prophecy you choose to believe is the one that comes true.

This is why the Commit-Be-Do framework from LIVE BIG is so powerful. When you commit to being a courageous leader before you have “proof” that you are one, you set a self-fulfilling prophecy in motion. Your behavior aligns with your identity, and reality follows.

Stanford University researcher Dr. Alia Crum has explored this mechanism through her work on mindsets and self-fulfilling prophecies, demonstrating that subjective mindsets, the lenses through which information is perceived and interpreted, can alter objective reality through behavioral, psychological, and even physiological mechanisms. Her work, inspired in part by placebo effect research, shows that changing what you believe about yourself can change what your body and brain actually do.

Why Women’s Courage Is an Organizational Imperative

This isn’t just about individual empowerment. There’s a hard business case for cultivating courage in women leaders.

The McKinsey Women in the Workplace 2024 research found that companies with more women in leadership, and where women’s representation is increasing, are more likely to prioritize supporting women across the organization. This creates a virtuous cycle: courage begets visibility, visibility begets representation, and representation begets organizational change.

Yet the same report found that only about half of surveyed companies say women’s career advancement is a high priority, and fewer are prioritizing women of color’s advancement. Companies have actually invested fewer resources into women’s advancement in recent years, offering fewer mentorship, sponsorship, internship, and recruitment programs geared toward women. In 2024, only 16% of companies offered formal sponsorship programs with specific content for women, down from 24% in 2022.

This retreat makes individual courage even more critical. When organizations won’t build the ladder, women must learn to climb without one. And the Fear Zone is exactly where that climbing gets hardest.

The McKinsey research also confirms what Herminia Ibarra’s HBR work suggested years earlier: women’s advancement is not limited by ambition. The 2025 report specifically noted that when women receive the same career support that men do, the gap in desire to advance falls away at all career levels. The problem isn’t women’s will. It’s the environment that either nurtures or suppresses that will.

Taming the Inner Critic: What Neuroscience Teaches Us About Limiting Beliefs

In LIVE BIG, I introduce a character called “Grumpy Greg,” the inner critic who sits in a cage on your right shoulder. When your subconscious mind is running the show, it tends to leave the cage door wide open for Grumpy Greg. Suddenly, you’re hit with waves of negativity: “You’re not qualified.” “Who do you think you are?” “Play it safe.”

These limiting beliefs often formed in childhood, shaped by family messages, cultural norms, personal experiences, and media portrayals of success. They operate in the shadows, influencing decisions without conscious awareness. And they are remarkably persistent, precisely because they’ve been reinforced through years of neural repetition.

But the same neuroplasticity research that shows your brain can build fear pathways also shows it can dismantle them. Here’s a practical approach I teach in LIVE BIG:

Catch Grumpy Greg in the act. The first step is awareness. Notice when negative thoughts creep in and visualize putting them back in the cage.

Challenge the narrative. Don’t accept limiting beliefs as truth. Is there actual evidence to support the fear, or is it simply a pattern your subconscious has been running on autopilot?

Declare “I am done with that.” This strategy, which I learned from neuroscience expert John Assaraf, involves making a conscious, verbal declaration that you’re releasing the limiting belief. Say it with conviction.

Affirm your power. Replace the limiting belief with an empowering one. Instead of “I can’t,” say “I’m learning.” Shift “I don’t deserve it” to “I am worthy of abundance.”

Practice progress, not perfection. There will be slip-ups. That’s okay. The goal isn’t to silence Grumpy Greg forever. It’s to reduce his influence over time by building stronger neural pathways for empowering beliefs.

The Alignment Advantage: Why Strategy Amplifies Courage

Courage without direction is just recklessness. In LIVE BIG, I teach the Boss² Up framework: aligning your Behaviors with your Outcomes, supported by the right Strategy, Skills, and Systems. When your daily actions align with your deepest goals, courage becomes purposeful rather than chaotic.

Think of it this way: the Fear Zone is where you summon the will to act. The Boss² Up framework ensures those actions actually move you forward. Without alignment, you might push through fear and take a big swing, only to discover you were swinging at the wrong target.

Strategic alignment reduces the cognitive load of courage. When you know exactly what you’re working toward, the decision to push through fear becomes clearer, because you can see exactly what’s at stake if you retreat. In my own journey, I went from a six-figure corporate salary to building a real estate portfolio from $50K to $2M in two years. That didn’t happen through blind courage. It happened because I committed to clear outcomes, identified the key focus areas (my “Watering Cans”), and then sprinkled them with daily action.

The combination of strategic clarity and personal courage is what separates leaders who burn out from leaders who break through.

Building Your Support Ecosystem

Courage isn’t a solo sport. Jim Rohn’s wisdom holds: “You are the average of the five people you spend the most time with.” If your inner circle is filled with naysayers, your Fear Zone gets larger and louder.

In LIVE BIG, I introduce two critical concepts for building your support ecosystem:

Your Energy Armor. Picture a clear, bulletproof plexiglass box surrounding you. It keeps your positive energy close while deflecting negativity from others. This isn’t about ignoring reality. It’s about controlling what you allow to penetrate your mindset. Those “energy vampires” who try to drain you? They bounce right off.

Your Inner Circle. Surround yourself with people who fuel your fire instead of dampening it. This includes mentors, mastermind groups, accountability partners, and communities of like-minded women. When you share your goals with supportive people, you’re not just getting encouragement. You’re establishing social accountability, which research consistently shows is one of the most powerful drivers of follow-through.

The Loyalty Loop: How Keeping Promises Builds Courage

Here’s a connection most people miss: self-confidence isn’t built through affirmations alone. It’s built through kept promises.

Every time you tell yourself, “I’ll tackle that project,” or “I’ll get to bed earlier tonight,” and then you follow through, you’re building trust with the most important person in your life: yourself. When you break those promises, your inner voice starts to lose faith. Self-doubt grows not from external criticism but from internal inconsistency.

This is what I call the Loyalty Loop in LIVE BIG. When your actions match your words, you see yourself as someone with integrity, someone capable and reliable. That self-trust becomes the foundation for courage. You stop second-guessing because you’ve established a track record of follow-through.

And the reverse is equally true. The biggest confidence killers are breaking promises to yourself and comparing yourself to others. Both erode the self-trust that courage requires.

Measuring Yourself by Your Own Ruler

Social media has created a comparison epidemic. We scroll through curated highlight reels and measure our behind-the-scenes against everyone else’s front stage. This is a fast track to the Fear Zone, because comparison breeds self-doubt, and self-doubt keeps you playing small.

The antidote? Measure yourself by your own ruler. Track your own progress. Celebrate your own wins. Use the Eisenhower Matrix to prioritize what actually matters. Journal your growth. And remember that the woman you were yesterday is the only legitimate benchmark for the woman you’re becoming today.

The Other Side of Fear

On the other side of the Fear Zone is where your inner strength wakes up. Where real growth begins. Where you find the BIG Zone, consistently operating at your full potential.

I didn’t just learn to walk in those red stilettos. I learned that the voice telling me to quit is just a voice. It’s not truth. It’s not destiny. It’s just the elephant (my subconscious) trying to keep me safe in a world that no longer requires that kind of protection.

The neuroscience confirms it. The leadership data demands it. The organizational research rewards it. Courage is not a personality trait. It’s a practiced skill. And every single tool you need to practice it is already available to you.

Your fear zone is not your enemy. It’s your gateway.

So the next time that voice whispers “retreat,” put on your metaphorical stilettos, take a deep breath, and keep walking.

The BIG Zone is waiting for you.
