What if imposter syndrome isn't what you think it is?

You're about to hit Publish on a LinkedIn post. You're about to tell someone what you do. You're about to launch a new offer. And then it starts. "Who am I to be talking about this?" "Everyone else knows more than I do." "What if someone asks me a question I can't answer?" "What if everyone realises I'm making this up as I go?"

Sound familiar? Welcome to imposter syndrome. Except… perhaps not in the way you've been led to believe.

Imposter syndrome has the habit of appearing just as you're about to do something important, convincing you that you're not experienced enough, knowledgeable enough or ready enough. It's easy to assume these thoughts mean something is wrong with you, or that they're a sign you're not cut out for business. But what if they're simply a sign that you're doing something your brain has never done before?

So... what is imposter syndrome?

Imposter syndrome, a term first coined in the 1970s, is the persistent feeling that you're not as capable as other people think you are. It convinces you that your achievements have come through luck, fluke, timing or circumstance rather than your own ability, and it leaves you waiting for the day someone will "find you out". It's a common experience, but having imposter syndrome doesn't mean you're an imposter. It means your brain is responding to uncertainty, and that's a very different thing.

Our brains are remarkable, but they're also incredibly practical. Their primary job isn't to make us successful, but to keep us safe. One of the ways they do that is by constantly making predictions about the world around us. Your brain loves familiarity because familiar situations are easier to understand and generally carry less risk. When you step into something new, however, your brain suddenly has far less information to work with, and that sets it into survival mode.

Starting a business is full of moments your brain hasn't experienced before. Charging for your expertise; creating content; networking; selling your services; calling yourself a business owner. None of these things are dangerous in the literal sense, but your brain doesn't always distinguish between physical danger and social risk. To your brain, uncertainty can feel like a potential threat, so it does what it's designed to do: it tries to protect you.

What do I mean by this? Well, imposter syndrome doesn't operate in the here and now. instead, it bombards you with risks, which either take the form of"What if...?" questions, or thoughts, and quite menacing ones at that.

"You're not ready."

"Everyone else knows more than you."

"You should wait until you've got another qualification."

"People are going to judge you."

These thoughts can feel convincing, but they're not facts. They're predictions. Your brain is trying to reduce uncertainty by encouraging you to stay where things feel familiar. It doesn't analyse the swaths of evidence that point to the fact that you are capable.

Why this feels so common after leaving corporate

For years, you worked in an environment that constantly reassured your brain. You had a job title, a manager, performance reviews, colleagues, clear expectations and someone else defining what success looked like. There were milestones to reach, promotions to aim for and regular feedback that told you whether you were doing well.

Then you start a business, and suddenly, literally overnight, you're responsible for everything. You're making decisions without certainty, putting yourself out there publicly and asking people to trust you based on your own expertise.

It's hardly surprising that your brain starts asking questions.

To stave off the fears of failure or judgement, you might turn to procrastination. You can spend an entire day replying to emails, tweaking your website, reorganising folders, watching tutorials, posting on LinkedIn and rewriting your bio, and still have avoided the work that truly matters. Tasks are easy to fill a day with, and can make you feel like you've achieved something, but this repeated action will keep you stuck in the longer term. That mental load is real, so being intentional is vital.

Rethinking imposter syndrome

This is what I mean when I talk about the Corporate Hangover. Many of the thoughts we experience in business aren't signs that we're incapable; they're the natural result of moving from an environment built around certainty into one built around uncertainty. Your brain is adapting to an entirely different way of working, and adaptation takes time.

This is also why I think we need to rethink the way we talk about imposter syndrome. It's often treated as something we need to eliminate, as though confidence is the goal and uncertainty is a problem to solve. But confidence isn't the absence of uncertainty. Confidence is what develops after we've repeatedly shown ourselves that we can handle uncertainty.

In other words, confidence doesn't come first. Action does.

Every time you do something your brain considers unfamiliar, you collect evidence. Every conversation you have, every client you help, every post you publish and every presentation you deliver gives your brain another piece of information to work with. Over time, what once felt uncertain becomes familiar, and what becomes familiar starts to feel safe. This is one of the incredible things about our brains: they're constantly adapting. They create and strengthen neural pathways based on our experiences. The more often you take positive action, the more your brain learns that these situations aren't dangerous after all.

What to do when it shows up

The first step is to recognise it for what it is. Rather than assuming the thoughts are true, remind yourself that your brain is trying to protect you. You can even give that inner voice a name if it helps create a little distance. Instead of thinking, "I'm not good enough", you might smile and say "Oh, Barbara's back again" . It sounds simple, and probably a little silly, but separating yourself from the thought makes it much easier to question it and control it.

Next, look for evidence instead of emotion. Our brains naturally pay more attention to potential threats than past successes, which means one difficult moment can outweigh dozens of achievements. When those familiar thoughts appear, ask yourself, "What evidence do I actually have?" Think about the people you've helped, the problems you've solved, the positive feedback you've received and the challenges you've overcome. Feelings make predictions, but evidence tells the real story.

It's also worth taking confidence from your past. Starting a business might be new, but overcoming challenges isn't. You've almost certainly learnt new skills before, managed difficult situations, led projects, solved problems and achieved things you once thought were beyond you. Your brain has navigated uncertainty hundreds of times already. Reminding yourself of that history helps it recognise that this situation isn't entirely unfamiliar after all.

Another habit that's well worth developing is celebrating small wins. Not every achievement deserves a fanfare, of course, but your brain notices what you repeatedly reinforce. If you only ever focus on what hasn't happened yet, your brain receives very little evidence that you're making progress. By acknowledging the conversations you've had, the content you've created, the confidence you've built and the milestones you've reached, you're strengthening the neural pathways that remind your brain you're capable.

Perhaps the most important thing, though, is to act before you feel completely ready. We often believe confidence has to come first, but in reality it's usually the other way around. Action creates experience, experience creates evidence, and evidence builds confidence. Waiting until you feel certain often means waiting far longer than you need to.

A little note to finish

Remember that discomfort is data, not danger. Feeling uncomfortable doesn't automatically mean you're making the wrong decision. Sometimes it means you genuinely need more preparation, but often it simply means you're doing something you've never done before. Learning to pause and ask, "What is this feeling trying to tell me?" is far more helpful than assuming it's telling you to stop.

The truth is, that little voice may never disappear completely. Even experienced business owners have moments of self-doubt. The difference is that they've learnt not to believe everything it says. They have enough evidence to answer back with proof.

One day you'll look back at the version of yourself who questioned whether you were good enough to start. You'll smile because you'll realise she wasn't lacking confidence; she was collecting evidence. Every conversation, every client, every LinkedIn post, every awkward networking event, every offer that didn't sell, every lesson and every tiny success gave her brain another reason to believe she could do this.

None of those experiences made her worthy. They simply showed her brain what she'd been capable of all along.

And that's the thing about impostor syndrome. It doesn't usually disappear overnight, but it does pop up less and less. It gets quieter because your actions become louder, bolder, more confident.

So the next time that familiar voice appears, don't assume it's telling you the truth. Pause. Thank your brain for trying to keep you safe. Remind yourself that unfamiliar doesn't mean unsafe, and take the next small step.

Because your future confidence is built by the evidence you create today.
