If you make things (like art/crafts) - you can sell them, and market yourself for commission work.
If you like to write - publishing books or blogging (with ad support).
If you like sports like skiing, short of going professional, you can provide coaching/lessons, and potentially expedition (like mount climbing or safari).
If you like traveling, consider being a tour guide, or even a TV personality.
If you like to cook, consider catering, blogging, being a TV personality.
If you like to eat - blogging will help.
If you like to sing/music - try to record your own music and put it on Youtube. It worked for Justin Bieber. But definitely start play in local venues for sure - that's how Beatle got going.
If you like to gamble - you are at most a plane ticket away from your jackpot.
There are countless hobbies and countless ways to make money, if you are 1) passionate enough, 2) good enough, and 3) persistent enough to make it work, you'll find a way.
Good luck 😉
