What are your current living circumstances? As in, are you in a city, a suburb, or rural area? And do you have financial security and potentially a surplus?
I ask since many hobbies and things to learn could cost money, space, or both. When I used to be in a congested city with no financials, things I’d learn were mostly computer based: writing stories on LaTeX, making a html portfolio, etc. Later, I got into building and flying RC airplanes which truly takes my mind off things and gives a relaxation feeling while flying. Now, I attend various seminars and lectures of different disciplines since it’s a no-pressure way of learning random cool stuff.
I just loved the baseline aesthetics of LaTeX. I liked writing stories when I had an itch for it, and it feels a lot better when your work is formatted nicely. It was a fun challenge without having any consequences.
Do you journal? Journalling on its own feels nice in the long run, and would also look cool if written in LaTeX.
