Sometimes I won’t let myself draw things I WANT to draw because I haven’t been working on the things I HAVE to draw enough.
This creates a feedback loop of just plain ol’ Not Drawing At All
Let yourself draw goofy things or nerdy things or whatever effed up thing you can’t stop thinking about. It’s good warmup anyway. I mean, it takes like 20-30 minutes anyway if you haven’t drawn in a day or two or longer for your hands to actually tap back into that muscle memory and remember how move fingers, so… draw something silly for fun that you actually WANT to draw!
Take the advice I never take myself.
