Early teaching from my father was "the only person you are responsible to is yourself".
As a result if I ever said that I would do something that is what I did. ... never less, frequently more.
I therefore wonder about the points system here for attaining differing levels. In a world of increasingly aggressive antagonism because others believe that you are not entitled to your opinion it is comforting to know that others think the same as you and provide the support of solidarity by giving your response the thumb up. That is not praise just simple solidarity and so I frequently press to give the green lit thumb. I'm not praising, I'm in solidarity and I wish more would do it or express their reason for not.

Women get trained to do this -- your bully story is a classic example.. It's a tough fight to find your way out of it.

I don't think I "suffer" from Imposter Syndrome but when I first got my current job I did wonder if I had promised too much and that I might turn out inadequate, because it was very different from what I had done before. But within a month I was getting some praise from colleagues and I relaxed and realised that it was actually perfect for me. The skills I thought I didn't have weren't actually very necessary - and I can muddle by - while I found there were dozens of skills that I didn't know would be applicable and which turned out to make me a very valuable member of the team.

I always say I am an actor, how I portray myself in public is an act, it isn't me. I have been good at jobs I hated and didn't believe in, I act friendly to Johnny Public when the job requires it, I just grit my teeth a lot.

And then there's the other side of the coin.

Yes is the short answer. It doesn't really trouble me much, it's just an occasional dip into negative self indulgence. Part of that stems from not having a degree and for the last thirty years I've held jobs where everyone around me had or was pursuing a degree or two. Don't get me wrong, I'm pro formal education, it just hasn't worked out for me. I've been lucky too with regard to my "career". I do struggle with that word, "career". I like my job but it's a happy accident and I'd leave it tomorrow if I were to stumble across a giant pile of fuck you money. I feel a bit trapped by it as I'd be hard pressed to have the income I do now somewhere else without a degree. But that's probably another dip into negative self indulgence.

There is nothing wrong with acknowledging the progress you've made in learning a skill. However rarely did anyone learn anything alone. I will acknowledge my increasing skill but while also trying to mention who helped me get there. When learning something new there is a truth to: "Fake it 'til you make it. " Like @marga said this is more common with women than men. Denying your own skill or accomplishments is self-negating. Maybe find some way to be nicer to yourself? It's ok to stand up and be counted. I am about the same age as you so I know it can be harder to change decades old behavior but it can be done. Take care and good luck.

For me, it's not "imposter syndrome"; it's "there is no doer".

I am not "I"--I am a consequence of everything that has come before me, every circumstance that led to my birth, and every experience that influenced my development. (In Buddhism it's called "interdependent co-arising; everything "lacks inherency".)

I didn't decide to be born. I didn't choose my DNA. I didn't raise myself. I didn't control all the circumstances that produced opportunities for me to make decisions.

So I sang beautifully, or wrote a lovely poem, or performed a thoughtful deed--so what? Wasn't "me". Who cares, anyway? "I" don't need credit. There is no doer.

This is an ancient idea from India.

There are rude and people who just lack empathy everywhere just itching to cut you. So I've learned to use my inner dialogue as if I were speaking to a friend instead of the constant critic. Positive affirmations, Google it. And there's also allot to be said for being in the moment, instead of dwelling on past mistakes that can't be changed or obsessing over future catastrophic events that may never happen.

I think it's just about finding that healthy level of confidence. It's important to me not to take credit for something, good or bad, that I didn't do. In my dishonest teenage angst this led to awkward responses to compliments. "Looks like you're getting fit son. Athletics is teaching you something" having skipped athletics on more than one occasion "pretty sure I'm just not eating as much, dad" like I said I was (still am) very akward.

If it comes down to needing attention, because that is what recognition is, attention. Now in a job situation, it can be more than that...money, position, power. I don't have a lot of use for accolades. Conceit for standing up to a bully? That is a new one on me...I've heard hippies call it aggression, but not conceit. If you like attention, then go for it. But if you can't, then shyness? Imposed belief systems of any kind can cause neuroses...so maybe your's did. I had a rough life during grade school which probably caused me to not want the lime light.

Hmm... didn't know there was a name for it either. I too, have been shy of praise. Especially professional praise. Not sure of when that started really; but it's definitely there. I once put my head to it, as you did, and found that my reason for feeling "fraudulent" was because it was SO easy to me, that I didn't feel it deserved attention. (I work in IT, so everything we do is "magic" to end users.. lol) I do get your point thought, ma'am.

Yup, especially women. We're taught to be humble and attribute our talent or success or accomplishments to God or luck or anything besides our own ability. To do otherwise is considered "unfeminine" or, as you said, conceit. This is not so prevalent with men, however; they are taught to not only be proud of anything they do, but to let other people know about it.

I don't do well with compliments either even though I want them. I'm especially worse at acknowledging them.
