I've got quite a few interests you could probably list as "passions", but probably the biggest source of casual enjoyment/time waste nowadays is video games. Everything else I do is somehow linked to learning skills, or bettering myself in general, but gaming is nowadays mostly a casual social experience for me.
I used to play competitively and take gaming more seriously, striving to improve, and I did get to a pretty decent top level in some games. I know a lot of people from that field, so I occasionally get to punch above my weight with some seriously good players, especially in strategy games that I am really quite bad at.
I trained myself to be a very much so above average RTS gamer with some high level coaching recently, but I wouldn't say I'm exactly top level.
Nowadays all I really do is play RTS and MOBA games with friends, or hop onto a server in Project Reality or Squad and lead some randoms.
People always go on about how hard or stressing it is, because you need to get random people you don't usually know to do things cohesively in a group with just verbal commands. Leadership skills are obviously required.
It's not that hard for me, but I guess after half a decade, it becomes routine.
Lately there's been days where I didn't launch a game and just read the whole day or worked on something, but I guess that's not a bad development.
