At least for the last one: I can’t recommend enough just going for it, not being afraid of getting it wrong. The health benefits of weight training are very well documented, it leads to a longer life and slower aging, which will give you more time for the other topics! And you’ll feel better to boot. Give it a go, treat it like a puzzle, you can do it. It’s a skill you continuously hone. After you’ve learned the basics it can be done under 1h per session, and 3 times per week is already huge. Even 1/week is good! :) Good luck!
