Posting this mostly for myself - a single place to keep all my thoughts, ideas and reminders on what to do or not do in order to get better at drawing.
Not much here at the moment, but I'll keep expanding it.
Work smart, not hard. Make sure you're enjoying what you do and take breaks when you aren't.
Try Photography, 3D modeling, AI image generation, or even just looking at photos and art, or playing certain games. There are many activities that develop the same skills that you need for drawing, even when it's not obvious.
