I understand why I feel like an impostor. So why do I still feel like an impostor?

You've figured out where your impostor feelings come from. You can identify the exact competence beliefs creating unrealistic standards that drive the anxious feeling you're fluking success. So why do you still feel like an impostor even with all that insight? In this article, we explore the idea that to really loosen the grip of Impostor Syndrome, we need more than insight. We need to have experiences that show us our old beliefs about competence are outdated, and that it's safe to rewrite them.

What it actually takes to change competence beliefs

Most people try to think their way out of Impostor Syndrome.

The problem is that the underlying competence beliefs fuelling impostor feelings aren't just intellectual.

They're experiential.

They're conclusions you've drawn after years of interpreting experiences in a particular way.

If you've spent years believing:

"I need to get things right the first time." (Perfectionist belief)

"If I need help, I'm not good enough." (Soloist belief)

"People will only respect me if I know all the answers." (Expert belief)

"I need to juggle everything flawlessly and never drop any balls" (Superhuman belief)

"I should be able to figure things out quickly and effortlessly" (Natural Genius belief)

Then reading an article that tells you otherwise isn't likely to create lasting change.

Your brain needs repeated exposure to new evidence to even consider the possibility that it's safe to let go of old, unhelpful beliefs and entertain new, more helpful beliefs.

The good news is that evidence is exactly what action gives you.

Every time you behave differently, you create an opportunity to test whether your old belief is actually true, or not. This is where the real change starts.

Let's experiment with 5 ways to gather new evidence

1. Pursue excellence, not perfection

If your belief is:

"I need to get everything right."

Your experiment is not to think differently; it's to deliberately DO something differently.

Submit, share or finish something at 80% good enough and then watch what happens.

I predict you'll discover that the world keeps turning even if there was a mistake in the document!

I predict your project will still succeed. People will still value your contribution.

I predict that perfection will start losing some of its credibility as the only pathway to success.

When you're no longer holding yourself accountable to standards of perfection, you'll be free to actually internalise successful outcomes rather than instantly discount them like you usually would... "I might've done well but I still made mistakes along the way, so clearly my success was a fluke. See? I'm totally an impostor." And when you start internalising that you were actually successful, you instantly circuit-break all the patterns reinforcing your impostor feelings.

2. Focus on incremental improvements and learning, versus proving yourself

When we experience impostor feelings, we tend to approach every achievement-related task outside our comfort zone as a test of our worth.

The anxiety-provoking question becomes:

"Can I prove I'm competent?"

A far more useful question is:

"What's opportunity is this task offering for growth and learning?"

When our goal shifts from proving to improving, mistakes stop being evidence of failure and start becoming evidence of growth.

Over time you gather proof that competence isn't something you demonstrate.

It's something you develop.

3. Ask for help earlier than feels comfortable

If you're carrying around a Soloist belief that capable people should figure things out themselves, try running a different experiment.

Ask for help sooner.

Pay attention to what happens next.

Do people think less of you?

Or do they simply see a smart person leveraging the strengths and resources available to them?

Many leaders are surprised to discover that asking for support often increases trust rather than diminishing it.

4. Give yourself permission to be a beginner

Natural Genius beliefs tell us that competent people should learn quickly and effortlessly. Setbacks or struggles become a reflection of our incompetence.

But that's not how learning works.

Pick something where you're guaranteed to be average, awkward, or slow.

It could be a new sport. A new skill. A new technology.

Then pay attention to what happens when you persist anyway.

You'll start collecting evidence that competence isn't about immediate, flawless performance.

It's about the courage to stay in the game long enough to improve.

5. Keep an evidence file

The part of you that feels like an impostor is an excellent prosecutor.

It's constantly gathering evidence against your competence.

So, start acting as your own defence lawyer (aka call on your Inner Coach!)

Create a document, notebook or folder where you capture:

• Positive feedback

• Wins

• Problems you've solved

• Difficult conversations you've handled

• Things you once found hard that are now routine.

This is not because you need constant reassurance.

It's because human memory is selective and guided by the brain's negativity bias; our tendency to fixate on all the things that went wrong versus right.

When impostor feelings show up, it helps to have actual evidence sitting in front of you that says, "See? Even though you weren't perfect, you needed help, and you hard to work hard to figure it out, you still succeeded. People still valued your contribution. You're not an incompetent impostor. You're a human trying their best to figure it out as they go just like everyone else."

Take home message

Understanding your Impostor Syndrome is valuable.

It's the first crucial step to freeing yourself from its stressful, limiting grasp.

But awareness alone rarely changes the deeply held beliefs about competence driving the experience.

Those beliefs change when reality starts giving you different data.

Every time you pursue progress over perfection.

Every time you ask for help.

Every time you try something new.

Every time you stay in the room despite feeling uncertain.

Every time you're willing to run an experiment.

With enough experiments, the old story starts to struggle under the weight of the evidence.

Owning your competence isn't built by convincing yourself you're capable.

It's built by repeatedly discovering that you can handle far more than your impostor voice would have you believe.
