Hobbies are not for making money. That’s what a job is for. Hobbies are where you sink the money you have left from your job and all the other expenses are paid.
That said.
Hobbies for me include:
Hiking (lots of good trails nearby)
Making sounds on my Synth (I’m building a case right now)
TTRPGS (when you can wrangle enough folks)
Skirmish Games (mainly Gaslands)
Video games (slay the spire, and casual WoW)
IMO as soon as a hobby produces any sort of money, it becomes a side gig. Maybe not a profitable side gig, but a side gig none the less.
