I got into leatherworking during the pandemic and it’s been really rewarding. The actual act of cutting and sewing the leather is very zen to me, and in the end you have something new that you can use or give as a gift!

Getting started is fairly cheap (some punches, needles, thread, a sharp knife, and leather is all you really need to get started). I order everything online so no need to interact with people.

Lots of good tutorials online to learn (Carter leather, weaver, are both good YT channels)

I’d anyone is interested in trying it I’d be happy to help get you started 😊

Climbing/bouldering at a bouldering gym, its sociable but since its often a solo sport you can leave any time.
Also every climber I’ve come across is very chill, and its good exercise.

This is going to go against what a lot of people will tell you, but my thought is that you should try to challenge yourself to be social and learn to develop those skills, rather than continuing to develop antisocial skills in your comfort zone. To that end, I’ll suggest you look into things like Toastmasters or another public speaking club, and tabletop RPGs - in person, not on Discord. You will have to overcome the challenges of being social and learning at the same time, but I think that those would be valuable experiences for you. Local boardgame groups will also be helpful, as you’ll be able to focus on the game rather than the socializing.

Everyone needs to learn how to be social. Don’t hide from it.

Disc golf. It can be very cheap to get started. Most courses are free. It gets you outside and in nature.

It can be as social or solo as you want. I like to play alone because then I can take all the time I want to throw/rethrow as long as I don’t have people coming up behind me.

Reading

Creating/writing/producing music, playing somewhat chill MMO games (often solo), walking/hiking in nature/interesting urban areas I haven’t fully explored before. Drinking a beer in late afternoon while sitting out in nature, just letting my thoughts run free and enjoying life (if that counts as hobby, or just an activity I do most days). Those all get me pretty far and never drain me like extroversion activities do.

Do the Blender donut tutorial and learn 3D modeling. It’s free. It’s a great time sink. Amazing online community. Personally, I find it very rewarding. I learned during lockdown and it’s one of my favorite accomplishments and I still have so much to learn.

Running.

• Lockpicking
• Rubiks Cubes
• Raspberry Pi stuff.
• Narrative driven Video games, obviously
• Cooking

This is going to sound a little strange, but playing music on stage works for me. At least in moderation, and provided you aren’t the lead singer/MC who has to interact with people. You just wanna be some guy in the corner jamming on whatever you jam on.

You kind of get the best parts of being in a social situation in terms of seeing new places, having interesting experiences you can ponder for days to come, and occasionally getting free food and/or a green room where you can veg out in isolation and no one expects anything of you. But you can avoid the negatives: having to make small talk, looking awkward with nothing to do and no role to play, being labelled antisocial, getting roped into some horrible activity you did not sign on for, etc.

And it turns out there are a lot of introverted musicians. You only really need one extravert in a band.

Programming (python), making music/learning instruments and synths.

Metal detecting, provided it’s legal where you live.

I put on headphones (ANC transparency mode enabled) and jam out while bicycling for an hour daily. I put over 3,000 miles on my Trek Verve2 annually
