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.
The cost barrier of entry is decently high though. Fly fishing is a huge rabbit hole for sure. I’ve never been but one of my coworkers goes almost weekly.
You can buy like $50 kits or go on Craigslist and look for someone selling their impulse bought gear.
Add in a license fee and even then it’s not too bad for time killing hobby.
I think when I first got into it I was put off thinking I’d need like the finest $3k in orvis gear and I’d need to buy $10 flies at my local shops.
Like there’s a weird bougie-classist feeling I think a lot of people have which turns them off of trying to get into the sport.
