The impostor feeling has a specific structure, and it is worth being precise about it, because most advice on this misses the part that matters.
Low self-confidence is a general underestimation. The impostor feeling is narrower and more stubborn: you have evidence that you are competent, you know the evidence is good, and you discount it anyway in favour of a conviction that you do not belong. Both things can be true at once, and the second one is the one that does the damage.
The other thing to be clear about is what this is not. It is not the same as depression, although they overlap. It is not a sign of a lack of ability, and the people who experience it most intensely are frequently the ones with the most evidence against it.
Why the evidence does not help
Here is the mechanism, and it is the reason every piece of advice you have already been given failed.
The discounting rule. Positive feedback gets attributed to luck, timing, being liked, the task being easy, the other person being generous, or the requirement being lower than you think. Each of these is plausible. There is a version of this for every piece of good evidence, and that is exactly what makes it self-sealing: the rule has no exception.
The bar moves. Every achievement sets a new standard rather than satisfying the old one. You present, it goes well, and now you are anxious about the next one. This is why the cycle does not terminate on success.
The comparison is unanchored. You compare yourself to the strongest available example rather than your own prior state. And crucially, you compare internals to externals: other people’s confidence, against your own doubt. Everyone else is doing this too, which means everyone else looks like they know what they are doing.
Being realistic does not help. If you lower your self-assessment to match how you actually feel, the feeling does not follow the assessment. You end up accurate and miserable, which is a worse position than inaccurate and confident.
A suggested tool
A notebook kept for evidence, not reflection
This is the one place in the site where a notebook is used as an archive rather than a reflective tool. The entries are short and factual, and the only thing asked is that you write down what happened rather than how you felt about it.

What helps instead: collect evidence
The most reliably effective approach is to change the task. Not from feeling better to thinking better, but from reassurance, which feels good and evaporates, to evidence, which feels flat and accumulates.
1. Keep an evidence file. A note, a document, wherever. Every piece of feedback, every completed thing, every time someone relied on your work, every problem you solved. Write what happened, in plain factual language. Do not write how you felt about it. The point is that when the feeling arrives, you have somewhere to look that is not your memory, and your memory under this condition is not reliable.
2. Date the entries. Not metaphorically. The point is to create a record you can re-read, and a record you can re-read is not the same thing as a recollection you are currently arguing with.
3. Use a colleague, not a compliment. Ask someone specific what they need from you in your role and write down the answer. This is much harder to discount than praise, because it is not evaluative of you, it is descriptive of the work.
4. Audit the attribution. When the feeling arrives, write down the explanation you reached for. Good luck. Too easy. They liked me. Then write down whether that explanation is consistent with what actually happened. Do this three or four times, then read your own list. Most people find the pattern obvious in the aggregate and invisible in the moment.
The part that is not evidence work
Evidence work addresses the belief. It does not address what the belief is doing to you, which is usually one of three things: avoidance (you decline work you are qualified for), overworking (you never submit anything you think is finished), or smallness (you shrink the claim you make about your own work).
If any of those is happening, the useful move is a behaviour, not an insight. Submit the thing. Take the project. Say the larger number. This will feel wrong, and that feeling is the impostor feeling doing its job, which is not to be accurate but to keep you safe.
Our page on self-compassion when you feel small is closer to the emotional side of this, and how to pause before you reply covers the specific moment where you accept an assignment you did not want because saying no felt too risky.
The parts that usually get skipped
The early context. It is worth asking, once, where the conviction came from. Frequently it is not new. For many people the earliest version is a family in which competence was only acknowledged when it was useful, or a school or workplace where being found out was the central risk. This is shadow material rather than a current problem, and our shadow work for beginners is a reasonable place to look.
Being new. A genuine part of the feeling is simply that you are new, and that is uncomfortable in a way that is easy to misread as fraud. Being new means everything takes longer and there is a body of context you do not have yet. That is a description of a stage, not a character flaw.
Genuine gaps. Some of the self-doubt is accurate. You may not know things you are supposed to know. The useful move is to find out precisely which gaps, and to close them by asking rather than by spiralling. Impostor feelings have a way of making a small gap feel total.
When it needs more than this
Reflective practices have a modest evidence base. Nothing on this page is a treatment. If the feeling is accompanied by persistent low mood, sleep or appetite changes, difficulty functioning at work, or if you have started avoiding things you used to do, that is worth talking to a qualified health or mental-health professional. Anxiety is treatable, and this is one of the more treatable presentations of it.
