Imposter syndrome is the persistent feeling that you don’t deserve your success — that you’ve somehow fooled the people around you and it’s only a matter of time before you’re found out. It’s remarkably common among high-performing professionals, and it doesn’t necessarily fade as your career progresses.
What Imposter Syndrome Actually Looks Like at Work
It rarely announces itself clearly. More often, it shows up in patterns you might not immediately connect: over-preparing for every meeting, dismissing praise as luck, avoiding situations where you might fail, or undercharging for your work. It can also look like perfectionism — spending twice as long as necessary on tasks because anything less than perfect feels like evidence of inadequacy.
These behaviours have real costs. They create chronic stress, limit the risks you’re willing to take, and can hold you back from roles or projects that would accelerate your development.
Why It Persists Even When You’re Succeeding
Imposter syndrome often doesn’t respond to external evidence. A promotion doesn’t fix it. Good feedback doesn’t fix it. This is because the feeling is grounded in internal attribution errors — you explain your successes as luck or circumstance, while your failures feel like proof of who you really are. The bar for evidence of competence keeps moving.
It’s also worth knowing that imposter syndrome can be more intense in environments where you’re one of few people with your background — whether that’s industry, educational history, or demographic identity. The feeling of not quite fitting in amplifies the sense of not quite deserving to be there.
Practical Approaches That Help
- Keep a record of your wins. Not a polished portfolio — a raw, private list of things you did well, problems you solved, moments colleagues relied on you. Read it when the feeling hits.
- Name the feeling out loud. Saying “I’m having an imposter moment right now” — to yourself or someone you trust — reduces its grip. It separates the feeling from fact.
- Talk to peers. Most people with imposter syndrome assume they’re alone in it. Direct, honest conversations with colleagues often reveal the feeling is nearly universal among high performers in demanding environments.
- Separate preparation from avoidance. Some preparation is useful. Preparing beyond the point of diminishing returns is a symptom, not a strategy. Notice when you cross that line.
What a Mentor Can Offer Here
A good mentor can help calibrate your self-assessment against an experienced external view. This isn’t about being told you’re great — it’s about getting honest, informed feedback that helps you build a more accurate picture of your strengths and gaps. Over time, this replaces vague dread with something more manageable: a real understanding of where you’re strong and where you genuinely need to grow.
Imposter syndrome isn’t a character flaw. It’s a cognitive pattern — one that can be disrupted with the right habits and relationships in place.
