Tangential, I've wondered recently if it's possible to work only when you want. A lot of people talk about working just enough to pay for necessities, but I'd rather work a little bit to cover those necessities, then have most of my time where I can either live or choose to work on demand, i.e. to support hobbies that can get expensive.
I guess it depends on the basic living standard. If you say, I can not work and keep the same standard of living I have now then I'd probably travel more.
Take a motorcycle trip around the world or something like that. Canoe down the nile. Sail to Antarctica. Stuff like that.
I have a small flat in the city, a little junk food, and no car. I'll be totally honest - from time to time I feel a little twinge of regret, since I could afford a McMansion and an expensive car if I worked all the time. But I quickly remember that I probably like the idea of those things much, much more than I would like actually having them. Especially at the expense of having to work all the time.
I would still program computers, probably around AI and cyber security, network security. Sleep lots because I love it. Spend a few hours a week doing something new.
