I am at a point now where I - when I get this "imposter syndrome" feeling - realized that what I am scared of is unfriendly programmers. It helps framing it like that, because it is so much easier to deal with something when I realize that is what I worry about.

I am not so worried about being good enough (I am what I am, neither more nor less), but I am a bit worried about someone knowing more than me trying to make me feel dumb.

But that is really just being afraid of bullies, and I am not... So once I frame it like that, it is more like "ok, so how would I deal with someone like that". And then it boils down to either someone being a bully unintentionally or intentionally.

The unintentional bully is not so hard to deal with, it is mostly about being friendly and curious, and their awkward behavoir can be turned around to an interesting conversation...

The intentional bully is something else, but they are also something I can deal with.

Anyway, this feeling-stuff I have been reading up on lately makes me realize it is not so much about not being good enough as being scared of someone bullying you for not knowing everything about a topic etc. And understanding that helps.
