Painting minis can be really relaxing while doing something else. If you’re participating in an RP in-game, or doing some kind of D&D online (like Roll 20), you can listen along or read along until it’s your turn while you cut, glue and paint.
Things I found that are helpful include a desk lamp, a magnifying glass, and definitely grab one of those mini holders so you can easily rotate it or place it how you want.
Oh, and get something to mix paints on. Can be a plate or lid if you’re cheap.
