I felt like an idiot for a long time when I didn't know what I was doing. Still do, sometimes, esp if I'm fully sober (social anxiety yay). And in the beginning it wasn't enjoyable, either, I wasn't doing it initially to have fun, but was tired of standing on the wall or at the bar every time I went to a place or event with expected dancing (and there are LOTS of these, particularly in your 20s). It was surprising when I found myself enjoying it, now it's surprising when I don't.
