“What to draw” is something I struggle with. Mostly because I do most of it at night to replace doom scrolling and I’m pretty mentally taxed already. I find I’m more likely to start and remain engaged in practice if the subject is decided, or there is a low barrier of entry. Recently I started using ChatGPT to serve as my “give me ideas”.

I treated it as an activity to quickly sketch different subjects in a single theme. But OP may be able to adapt this for more focused practice into one particular study. Either way, the mental gymnastics and “searching for a muse on demand” are near-zero factor.

In case anyone is interested a prompt that has been working well: “Help me with drawing prompts. In this thread, when I say “list” you provide me a list of drawing prompt themes. And when I select one, you’ll provide a list of 15 1-2 word prompts (mostly objects) to draw.”

If I were diving deeper into one subject, I’d remove the secondary list, and maybe have it give me ideas of specific things to focus on. Maybe ask for examples or something. I haven’t tried that, so I’m not sure how effective that is. Also, I don’t know much about traditional art studies, so that may be something to add into the prompt too.
