I don't really care about social awkwarness, but I'm annoyed that I used to be really good at presentations and training people, and I suck right now, because of lack of practice. And I didn't even actively practice before the presentation, I just jotted down a few ideas and was really passionate about the subject matter. Nowadays I find a lot of times that I stumble mid idea, forget what I was trying to show and generally break my flow a lot and find myself in "oh, snap, where did I lose them exactly?"

A couple of years of working as a contractor, changing jobs more frequently, the lockdowns and I didn't do a lot of presentations/idea sharing.

So yeah, practice and remember if you don't use it, you lose it.
