I recently got into video game development, and I’ve had so much fun, and it’s given me some much-needed meaning. I’ve solved problems unique to my game using programming skills as well as game design skills, and it feels meaningful because i can send it to my friends and they can enjoy it without needing to appreciate any of the technical aspects. I get to be creative about how people I care about can have more fun. It could also involve your music composition hobby, since every good game needs some music and sound design! I’m a programmer for my day job so most things I do there are only meaningful to other programmers, and the problems I solve there are incredibly boring ones.
Edit: I saw your comment about being burnt out on programming, and I totally understand that. That happens to me frequently. I enjoy programming as a hobby when I’m not burnt out so we’re kinda in different boats there. There are lots of skills involved in making games and the variety has really refreshed me, though I’ve still gotten sick of sitting at a computer while working on it.
Homebrew is so fun, and I love how you can make it as complex as you want. Like, you can just mix some honey and some water (in the right ratio) and let it sit, and you’ve got mead! Or you can add flavors. Or experiment with yeasts. Or brew beer and experiment with hops and grains. It’s a hobby that really meets you where you want it to.
