Years ago, I wrote fiction, and dreamed about writing a novel (I was only able to write short stories). I assumed I liked writing per se. But I was hanging out regularly with a group of fiction fans... and when later a conflict happened between me and them, so that I stopped meeting them completely, I found out I had no desire left to write fiction anymore. So, seems like this was actually about impressing specific people.
I got the message, "To fit in, you have to really be about the thing. No half assing it. No posing."
I suspect this is only a part of the story. There are various ways to fit in a group. For example, if you are attractive or highly socially skilled, people will forgive you being mediocre at the thing. But if you are not, and you still want to get to the center of attention, then you have to achieve the extreme levels of the thing.
In light of reading through Raemon's shortform feed, I'm making my own. Here will be smaller ideas that are on my mind.
