Thanks for giving me ideas to add to my 200 hobbies, miniature painting it is. I even have an app (Streaks) that reminds me daily of thousands of things I want to do, and it just shows how unrealistic it is. I want to concentrate on just two things, but then I hate to plateau on the other skill. Right now I concentrate on guitar and trumpet. But my painting and drawing skills are really not that good anymore. I try to also publish some academic papers, repair my bike, lift weights, run, get better at theorem proving, read into all of the social sciences, read philosophy (Kant, Hegel), experiment with Arduino, build a repertoire in Rebetiko ... If you find a trick to just do one things, tell me.
