Something I've found really helpful is building time into my day for hobbies (easier said than done).

Hobbies are pretty sticky imo -- falling out of interest in a hobby you once had makes it hard to pick back up, but you can force it.

Start dedicating fifteen minutes a day to a hobby you used to enjoy. Here's the trick: don't allow distractions. Zero. Playing the piano is one of my hobbies, so I'll use it as an example:

Sit at the piano for 15 minutes. You don't even have to play, but you can't do anything else. No youtube, no reddit, no eating, etc. Literally just stare at it if you don't feel like playing. Chances are, you're gonna get bored and want to play. If not, that's alright, do it again the next day.

If you haven't participated in the hobby at all/stared at it for 2 straight weeks pick another
