keep a running list of accomplishments

Great idea.

My favorite thing to do in this regard is to occasionally sit down and pinpoint things I was doing 1, 2, 3 years ago, etc. and allow myself credit for how far I’ve come since then.

I have a coworker who always recommends keeping a 'yay me' file or journal somewhere and trying to write 2-3 wins you had at the end of the day. Even if they're small. I started doing it recently, and it at least gives me perspective on what I'm doing well!

I have something called an impostor flashcard which is basically a list like this on steroids. So important to keep reminding yourself of your capabilities- the inbuilt tendency to self criticism has to be countered

The surface area of what you don't know gets bigger and bigger the more you learn. The amount of things you'll realize you don't know grows exponentially while your knowledge grows linearly.

In addition to a list of accomplishments, which is a great idea for representing how far you've come, make a list of things that are utterly baffling to you today and see if you can knock any of those off the list in the months or years to come.

Something that seems downright dizzying today you might learn and think is no big deal later on, but your past self would surely be impressed with what your future self can do.

Yeah, I have a document with a list of everything I've achived in my line of work.
I re-read it more times than I'd like to admit, but it keeps me away from the ImpSys for a while.
Ocasionally in a re-read I found out I'm missing something and I add it, that's a powerful feeling too.
The list keeps track of things I've achieved in terms of good feelings during work time, you can find a "Hello World" that I'm proud of as well as big contributions in a big team.
The key is to save that feeling, the feeling is what make you feel better when you are in "these days".

I say I've got Impostor Syndrome, but honestly I think I'm just faking it.

More seriously, recording accomplishments is good, but also keeping a list of "I'll be a bit more awesome when" goals. It's easy to disparage a recent achievement, while forgetting that a few months (or years) ago it might have seemed entirely out of reach.

Also, you clearly don't have impostor syndrome - you can't even spell it. ;-)

I was a Christian missionary working in a developing country. I was convincing myself that I was not the best person for the job I was doing (IT support) and that there were thousands of better qualified people in the world who could do a better job and should have been there making less of hash of it than what I was.

It didn't dawn on me until years later that whether I was the best fit or not, I was the one God had appointed to that role in that place at that time. None of those thousands had applied to that missionary society. No one else had shown the slightest interest in working in that fairly dangerous country. No one else had made it through the stringent testing and training regime.

I believed a lie. I spent years dealing with the depression aftermath.

We can be okay at stuff, and we call all do better.

This impostor thing doesn't limit itself to vocation. It attacks parents too. I'm okay as a dad. I could have done better in the kids early years. But they're not dead yet and neither am I. I can still be and do better. I'm not pretending to be their dad. I am their dad.

The only solution that I've found is to walk into situations with my brain turned off. Day by day it has become better.
