I have ADHD and my hobby is collecting hobbies. I don’t typically get bored. I would likely need to do some side gig to supplement buying things for new hobbies.
That’s my current situation after retiring a few years ago. I stay busy with personal software projects, running a weekly in-person D&D campaign and playing in others, cooking, 3d design and printing, Arduino/ESP and electronics, woodworking, reading, TV & movies, and random crafting and other stuff that comes up.
Read, learn, create, and explore.
Gardening, fishing, skiing, hunting, making furniture, building boats, long road trips with the family.
Basically typical retirement shit.
Short answer: work less.
Long answer: I actually enjoy my job, and have for a long time. If I had won several million long ago I would have kept my job because it (most of the time) was very fulfilling and important, though it has largely wrecked my body.
Now I can’t fly anymore, so while my job is still important and fulfilling, it’s not nearly as exciting, and I am constantly crazy busy, so I’d love to cut my hours about in half, probably. I’d still want to work.
Oh, and I’d build a forge in my backyard. So maybe work the same amount, but some of my time crafting things.
Write, read and analyze literature. Hopefully I’ll be able to do it as a job.
Become a blacksmith. I’d make all sorts of things.
And a welder. And a tool and die man.
I’d work with metal. And at some point I’d make a point to learn glass blowing because it’s cool.
Go back to the low paying job that I really liked but couldn’t afford.
I would make radio. I do one show a week and I sometimes struggle to find time to even prepare for that, so if time weren’t an issue I’d probably end up just doing a load more.
I’m into bird watching, so I’d want to travel to see new ones and what have you.
I would want to craft more.
I would read more.
I would take language lessons
I would work on that book idea
I would take classes on anything that interested me.
I would want to have a small farm, I just think it’s neat.
Would study and do arts and use our findings and research to help improve the world in some kind of way, even if its a little.
Without joking, most likely I would watch more Lemmy.
Join a 3rd band, I guess.
Get high and scroll Lemmy, apparently
Work to solve problems. Not on a fixed schedule, but my choosing.
Also, long walks and visiting people I like.
