@thor Not a small number of hobbies but a lot of hobbies which change if I will be able to do them for hours.
I learned to accept that they switch. It happens mostly without warning and I just accept that a new hobbies phase is there. Some never come back and others always will come back again.
RPGs is a hobby that is coming back very often if I play many different systems because it is enough variety but sometimes I need a couple weeks to month pause.
If someone is interested: the ones that always come back at some point are: lockpicking, programming, solving puzzles (jigsaw, Einstein, puzzle boxes, video games like baba is you), video games (Souls-like games and survival crafter like Minecraft especially because I decide when and how I engage the story of them for the most), board games, writing, building stuff (like robots, wood craft, miniatures, models, etc.), magic tricks, Rubik's cubes, RPGs, comics, books and a few more.
