I ask you guys for questions and draw whatever I feel like answering/writing about. Prompt generator. Also lets me work on my world-building even if I'm not drawing anything particularly good. Some of the best advice I got for blockages is as follows: If you can't draw well, draw it badly. If drawing just isn't working today, draw tomorrow. Take plenty of breaks and make sure to live your life. Artists can't create from nothing, you need to have experiences.
This advice can also go for writing, sculpting, almost anything creative.
