I don't understand how people find friends outside of work or school.

I've never really found people I get along with that I can hang with and I never really did in school either. I'm not sure how people do it these days to be honest. Your 20s are pretty much a time to try and make new friends, I believe, but I'm not very good at making them, I don't really know how. I'm pretty extroverted, but I think my main issue is that I have so many different interests that it's hard for me to categorize myself into an easy to find group. I like playing video games, working out, watching movies, dancing, playing Korean instruments, and basically anything else that sounds fun. I have a hard time finding people who have a similar collection of interests and are people I get along with.
