My two are:
Making sourdough. I personally always heard like this weird almost mysticism around making it. But I bought a $7 starter from a bakery store, and using just stuff in my kitchen and cheap bread flour I’ve been eating fresh sourdough every day and been super happy with it. Some loafs aren’t super consistent because I don’t have like temperature controlled box or anything. But they’ve all been tasty.
Drawing. I’m by no means an artist, but I always felt like people who were good at drawing were like on a different level. But I buckled down and every day for a month I tried drawing my favorite anime character following an online guide. So just 30 minutes every day. The first one was so bad I almost gave up, but I was in love with the last one and made me realize that like… yeah it really is just practice. Years and years of it to be good at drawing things consistently, quickly, and a variety of things. But I had fun and got something I enjoyed much faster than I expected. So if you want to learn to draw, I would recommend just trying to draw something you really like following a guide and just try it once a day until you are happy with the result.
Speedcubing. There are good cubes for < $10 now and beginner’s method is easy to learn. There are many resources online and can be learned within minutes. Then you start improving and getting faster quickly.
In my case I then went to a local competition and just amazed at how quick and how young these kids are.
When I got my first Rubik’s cube, I never thought I’d ever be able to solve it in under a minute. I still can’t, because it turns like garbage, but I got a 30 second solve on my MoYu cube recently.
I think the tricky part about getting people into speedcubing is them realizing that they shouldn’t buy Rubik’s cubes. I got one and just left it sitting for years because of how bad it is to turn. It wasn’t until I watched random YouTube videos before I realized I could enjoy it if I got a different puzzle
