I don’t think this is why you feel like an imposter, rather this is a rationalisation for why you feel like an imposter. It’s possibly to do 1 and 2 and not feel like an imposter, so this can’t be the whole reason. It might be necessary for some people some of the time, but it’s not a sufficient explanation. You even called yourself out on it later in your comment where you say it’s a fallacy. I’d hazard a guess the real issue is some kind of underlying generalised anxiety.
