As soon as you accept, not just “realise”, but actually and honestly accept the fact that there’s always going to be somebody more qualified to do whatever it is that you’re doing.. the imposter feelings will vanish ;) so yeah.. you’re not the most qualified. Absolutely all odds are all against you, in any case. So what? Just make the most of any opportunities you’re presented with and make your time worth while ;) That’s how I’ve dealt with it. Has worked well for me, would recommend!
