7 Mistakes You’re Making with Overcoming Imposter Syndrome at Work

Hello, my lovelies. Grab yourself a big brew, maybe a creamy cappuccino or a soothing peppermint tea, and find a comfortable spot to settle in. Today, we’re having one of those heart-to-heart chats that really matters. We’re talking about that loud, nagging voice that whispers (or sometimes shouts), “You’re a fraud. You don’t belong here. They’re going to find you out.” Yes, we are diving deep into the world of imposter syndrome at work, and more specifically, the mistakes so many brilliant women make when they try to overcome it in ways that look productive on the surface, but quietly keep them stuck underneath. If you’ve ever sat in a high-level meeting, looked around the room, and felt like you were just “playing dress-up” in a professional’s life, I want you to know: I see you, and I’ve been there too. Even as the CEO of Nefe Oguntoye Coaching, I’ve had moments where the internal critic has tried to take the wheel, especially in seasons of expansion, visibility, or personal pressure behind the scenes. There have been tender times in my own life where I’ve been navigating a lot privately, trying to show up well while also listening to my body, pacing myself, and carrying responsibilities people couldn’t necessarily see. And that, my loves, is often where imposter syndrome gets loudest: not because you are incapable, but because you are stretched, visible, and deeply invested in doing things well. The truth is, the way we’ve often been taught to “overcome” imposter syndrome is far too harsh, far too performative, and far too disconnected from what confidence actually needs in real life. We are told to simply “believe in ourselves”, speak more loudly, collect more credentials, or push through the discomfort until the feeling disappears. But that framework misses something important. For ambitious, thoughtful, heart-led women, imposter syndrome is rarely solved by forcing yourself into a louder version of confidence. It softens when you build self-trust, gather real evidence, create emotional safety, and learn how to stay anchored even while doubt is present. We treat imposter syndrome like a mountain to be conquered once and for all, but often it is a companion to growth. It tends to appear when you are entering a new room, leading at a higher level, charging more, speaking more publicly, or allowing yourself to be fully seen. That does not mean you are failing. It means you are stretching. Today, I want to share the seven most common mistakes I see brilliant women making when trying to navigate imposter syndrome at work, and how we can shift into a more grounded, honest, sustainable kind of confidence. This is the full conversation, not the polished little summary version. So we’re going deeper. We’re looking at the mindset patterns, the workplace habits, the emotional anchors, and the practical resets that actually help.

1. Waiting for the “Feeling” of Confidence to Arrive First

One of the biggest mistakes I see my clients make is waiting. Waiting until they feel 100% ready, waiting until the fear subsides, or waiting until they have one more certification before they take that seat at the table. My loves, confidence is not the prerequisite for action; it is the result of action. If you wait until the “imposter” feeling is gone, you might be waiting forever. The magic happens when you act while feeling like an imposter. Every time you show up despite the nerves, you’re providing your brain with evidence that you are capable. At work, this often looks deceptively responsible. You tell yourself you are being strategic, careful, or professional. But underneath that polished language is usually fear. You delay applying for the senior role until you have ticked every single box. You sit on a brilliant idea in a meeting because you want to word it perfectly. You wait to pitch your service, launch your offer, or speak up to leadership because you think confidence should come first and action should come second. But real confidence rarely works in that order. Confidence grows when you survive the thing you were scared to do. It grows when you contribute in the meeting and realise the room did not collapse. It grows when you send the proposal, have the difficult conversation, ask the question, or present the strategy and discover that you were more ready than your fear suggested. This is why so many women stay stuck for years. Not because they are not talented enough, but because they are trying to feel certain before they move. A more empowering framework is this: borrow courage, then build confidence. You do not need to feel bold every time. You just need a strong enough reason to take the next tiny, honest step. Sometimes that step is speaking once in the meeting. Sometimes it is sending your CV. Sometimes it is finally putting your rates on the page. Let the action be small if it needs to be. Just let it be real. If you find yourself constantly pausing, circling, and second-guessing your own instincts, you might want to read my thoughts on how to stop second-guessing your decisions and start trusting your gut. Confidence is built in the doing, not in the waiting room of perfection.

2. Using Over-Preparation as a Shield

Do you find yourself staying until 8:00 PM to perfect a presentation that was already great at 4:00 PM? This is what I call “The Over-Preparation Trap.” We think that if we work twice as hard as everyone else, we can compensate for being a “fraud.” In reality, this just leads to burnout and reinforces the idea that your natural talent isn’t enough. You start to believe that your success is only due to the gruelling hours, rather than your innate brilliance and expertise. It’s a subtle way of hiding. Now, let me be clear. Preparation is not the problem. Preparation is wise. Preparation is part of excellence. The issue is when preparation stops being support and starts becoming self-protection. That is a very different energy. One comes from professionalism. The other comes from panic. Over-preparation often shows up as:

• rewriting emails five times before sending them;
• rehearsing for every possible question before a meeting;
• saying yes to extra work so no one can question your value;
• collecting more qualifications than you actually need;
• spending hours perfecting details that barely change the outcome.

This pattern can look high-performing from the outside, which is why it is so easy to praise and so hard to spot. But inside, it usually feels exhausting. Loud. Tight. You may look composed while secretly feeling like you can never let your guard down. You may be producing excellent work while privately believing you are one mistake away from being exposed. That belief is the real issue. When your nervous system starts to associate success only with overexertion, you lose your sense of enoughness. You stop trusting your experience, your instincts, and your body of work. You convince yourself that the only reason you are doing well is because you are outworking everyone else. And that means rest starts to feel dangerous. My loves, that is not confidence. That is survival dressed up as professionalism. True growth comes from trusting that your “B-plus” effort is often better than most people’s “A-plus”, and allowing yourself the grace to be human. Set boundaries. Pace yourself. Submit the deck when it is strong, not when it is flawless. Let one task be complete without squeezing every last drop of energy from yourself. This is one of the gentlest and most powerful ways to loosen imposter syndrome at work: prove to yourself that competence does not require constant overextension.

3. Comparing Your “Behind-the-Scenes” to Their “Highlight Reel”

In 2026, we are more connected than ever, but that often means we are constantly bombarded by the polished versions of everyone else’s careers. You see a colleague’s promotion or a peer’s “effortless” launch, and you immediately feel like you’re falling behind. You are comparing your messy, internal process, complete with doubts and morning-hair, to their curated, professional output. This comparison is the thief of peace. When we focus on others, we lose alignment with our own purpose. This happens in workplaces all the time. You see someone speaking confidently in meetings and assume they never feel nervous. You see someone’s polished LinkedIn post about a promotion and forget the years of uncertainty that likely sat underneath it. You watch a peer launch a business, raise their rates, win an award, or step into more visibility, and suddenly your own progress feels small, delayed, or unimpressive. But comparison distorts context. You do not know what support they have. You do not know how many drafts sat behind that confident presentation. You do not know what they are struggling with privately, what opportunities they had access to, or what they have sacrificed to maintain that image. And even if they are doing brilliantly, that still tells you nothing negative about your own path. Imposter syndrome gets louder when you use someone else’s timeline as proof that you are behind. It gets louder when you copy someone else’s voice, strategy, or presence because you think their success means your natural way is not enough. This is especially true for ambitious women building a personal brand, growing a business, or moving into more visible leadership. If you are constantly editing yourself to look “more like her”, then of course you will feel fraudulent. You are performing instead of aligning. I often talk about this in the context of personal branding; if you’re making visibility mistakes by trying to mimic someone else’s path, the imposter syndrome will only grow louder because you aren’t being authentic to your magic. A gentler reset is to come back to your own anchors:

• What season am I actually in?
• What matters most to me right now?
• What have I already built that I am overlooking?
• What would aligned progress look like for me this month?

That is how you step out of comparison and back into purpose.

4. Attributing Your Wins to “Luck” or “Timing”

Listen to me closely: You did not get to where you are by accident. When someone gives you a compliment or you hit a major milestone, do you find yourself saying, “Oh, I just got lucky,” or “They were just being nice”? When you deflect praise, you are literally training your brain to ignore your achievements. Mistake number four is failing to internalise your success. This one matters more than people realise because your confidence is shaped not just by what you achieve, but by the meaning you attach to those achievements afterwards. If every win is dismissed as luck, timing, a helpful manager, an easy client, or some strange administrative accident, then you never actually let success land. You experience the evidence, but you do not absorb it. And when the next stretch moment arrives, you still feel empty-handed because you have not built a usable bank of self-belief. This can sound very modest on the surface:

• “I just happened to be in the right place.”
• “Anyone could have done it.”
• “It wasn’t that big of a deal.”
• “They probably had no one else.”
• “The team did everything, really.”

Now of course, humility matters. Teamwork matters. Gratitude matters. But constantly minimising yourself is not humility. It is self-erasure. There is a difference between acknowledging support and denying your contribution. You can appreciate timing and honour your preparation. You can celebrate your team and recognise your leadership. You can be grateful for the opportunity and admit that you brought skill, insight, consistency, and care to the table. Try building a more honest internal script. Instead of saying, “I was lucky,” try:

• “I worked hard for this.”
• “I handled that well.”
• “I added real value there.”
• “That outcome reflects my growth.”
• “I am proud of how I showed up.”

It may feel clunky at first, I know. Sometimes it even feels wildly uncomfortable. But discomfort is not always a sign that something is false. Sometimes it is a sign that you are speaking to yourself in a new way. And that is part of the work. If this feels difficult, start small. Keep a private evidence list on your phone or in a notebook. Record compliments, positive feedback, good outcomes, brave moments, and the projects you completed when it would have been easier to hide. Read it before meetings, interviews, reviews, and launches. Let your brain see the truth in writing. Self-belief becomes stronger when it has evidence to lean on.

5. Trying to Slay the Giant in Total Isolation

There is a specific kind of shame that comes with imposter syndrome. We think that if we tell anyone how we feel, the “secret” will be out and the charade will end. So, we suffer in silence. But isolation is where imposter syndrome thrives. It loves the dark. When you bring these feelings into the light, by chatting with a mentor, a coach, or a trusted circle of women, you realise that almost everyone you admire has felt the exact same way. One of the reasons imposter syndrome can become so intense at work is because professional environments often reward composure more than honesty. Everyone looks polished. Everyone sounds capable. Everyone appears to know what they are doing. So if you are struggling internally, it is very easy to assume you are the only one. You keep performing. You keep smiling. You keep hitting deadlines. Meanwhile, inside, you are carrying a heavy and tender story about not being enough. My loves, that kind of isolation is exhausting. You do not need to announce your deepest insecurities to everyone in the office, but you do need safe spaces where you can be real. That may be a mentor who can normalise your growth curve. It may be a trusted friend who reminds you of who you are when your inner critic gets loud. It may be a coach who helps you untangle the pattern at the root rather than just manage the symptoms. This is why I care so deeply about confidence work. The shift that happens when a woman realises, “Oh, it’s not just me”, is honestly one of the most beautiful parts of this work. Shoulders drop. Breathing slows. Shame softens. And from there, we can actually build something solid. This is why I love the work I do in my coaching sessions; seeing the relief on a woman’s face when she realises she isn’t alone is truly surreal and beautiful. If you’re navigating imposter syndrome at work, ask yourself:

• Who helps me come back to truth?
• Where am I pretending to be fine?
• What conversation am I overdue to have?
• What support would make this feel lighter?

Don’t try to do this by yourself, my loves. Confidence grows faster in safe, supportive spaces.

6. Confusing “Learning” with “Inadequacy”

Being a “beginner” at something new, like a new leadership role or a complex project, is often mistaken for being an imposter. There is a huge difference between being unqualified and being in a state of growth. If you are feeling out of your depth, it’s likely because you’ve had the courage to step outside your comfort zone. Mistake six is judging yourself for not knowing everything immediately. This shows up so often after promotions, career pivots, business growth, motherhood transitions, returning to work, or stepping into more visible leadership. You enter a new room where the expectations are higher, the language is unfamiliar, and the consequences feel bigger. Of course there will be a learning curve. But instead of treating that learning curve as normal, many women make it mean they never should have been there in the first place. That is such a painful misread. There is a difference between:

• “I am still learning this,” and
• “I am not good enough for this.”

One is factual. The other is shame. When we confuse learning with inadequacy, we become harsh with ourselves in ways we would never be with anyone else. We expect instant mastery. We panic over questions. We hide gaps we could easily close. We stop asking for clarity because we think needing support is proof that we are failing. But growth always includes not knowing. Leadership includes not knowing. Expansion includes not knowing. Give yourself permission to be a high-level learner. That means you can be smart, capable, and accomplished while still learning. You can be the leader and the student. You can be excellent without being omniscient. In fact, some of the most grounded, effective professionals are the ones who can say, calmly and confidently, “I don’t know yet, but I can find out.” That is not weakness. That is maturity. So if you are in a stretch season, create a more supportive framework around yourself. Ask better questions. Seek feedback. Build skills intentionally. Keep notes on what you are learning. Measure progress over months, not moments. Frame the gaps in your knowledge not as flaws, but as the next exciting part of your evolution.

7. Treating It Like a Problem to Be “Fixed”

This might sound counter-intuitive, but the biggest mistake is viewing imposter syndrome as a sign that something is wrong with you. Imposter syndrome is often a “companion” to growth. It tends to show up right before a breakthrough or a major transition. If you wait for it to disappear completely before you feel “healed,” you’re setting yourself up for frustration. This is one of the biggest shifts I teach: stop asking, “How do I get rid of this forever?” and start asking, “How do I support myself well when this shows up?” That change in wording matters. It moves you out of war and into relationship. It moves you away from self-rejection and towards self-leadership. Because the truth is, doubt may still visit you in bigger seasons. Before a keynote. Before a launch. Before a promotion interview. Before a bold boundary. Before a difficult conversation. Before the next level of visibility. The goal is not to become a robot who never feels fear. The goal is to become a woman who knows how to stay anchored, clear, and connected to herself even when fear is in the room. Instead of trying to kill the feeling, try to change your relationship with it. Think of it as a signal that you are doing something brave. When that voice pops up, acknowledge it: “Oh, hello again. I see you’re here because I’m doing something big today. Thanks for trying to keep me safe, but I’ve got this.” That is a much gentler, more sustainable framework than chasing a fantasy version of total certainty.

Small, Honest Steps for Today

If you’re feeling the weight of these mistakes today, let’s do a gentle reset together. You don’t need to change everything overnight. Just try these tiny shifts:

• Accept the compliment: The next time someone praises your work, just say “Thank you.” No “buts,” no “it was nothing.” Just “Thank you.”
• Audit your wins: Take five minutes today to write down three things you’ve achieved in the last six months that had absolutely nothing to do with luck.
• Name the pattern: Notice which of these seven mistakes shows up most often for you. Awareness is an anchor.
• Borrow evidence: Re-read a kind email, performance review, testimonial, or message that reflects your real impact.
• Speak it out: Share one thing you’re struggling with with a friend, mentor, or colleague you trust. Watch how the power of that “secret” shifts the moment it’s spoken.
• Take one brave action: Send the email. Share the idea. Apply for the role. Ask the question. Let one action become proof.

None of this is about becoming louder, harder, or more polished. It is about becoming more honest, more grounded, and more self-trusting. My lovelies, you are exactly where you are meant to be. The boardroom, the studio, the stage: wherever you find yourself, you have earned your place there through your resilience, your heart, and your unique perspective. And if imposter syndrome has been loud lately, please do not make that mean you are failing. Often, it means you are growing into a room your old identity has not fully caught up with yet. That is tender work. That is identity work. That is confidence work. And it deserves compassion, not punishment. Let this be your reminder that you do not need to prove your worth through exhaustion, silence, or perfection. You are allowed to learn. You are allowed to be visible. You are allowed to take up space before your inner critic gives you permission. Most of all, you are allowed to trust that your presence in the room is not an administrative error. We are all learning, all growing, and all navigating the tender spaces of our own potential. Don’t let a temporary feeling rob you of a permanent impact. If you’re looking for more structured support to navigate these shifts, feel free to explore my resources or reach out for a chat. Stay elegant, stay grounded, and above all, keep believing in the magic that is you. With so much love, Nefe
