WARMUPS
Get your word and image brain moving. Use as many as you need. Think of this like stretching before a run, a way of simply arriving in your writing mind without the distortion of any particular focus or pressure. Disregard correctness and intention; keep the windows and doors open.
here's a warmup prompt dialed up at random

Lynda Barry’s daily diary
Do Lynda Barry’s 4-minute diary. (It’s actually 7 minutes, but I like to do a speed version in 4.) Draw a box on a page, taking up most of the page. Then draw a line vertically down the middle, and another toward the bottom to make two long columns and two square boxes. In the first long column write DID. In the second, SAW. The left box, OVERHEARD. Then setting the timer, write down 7 things you did in the last 24 hours in the DID column, 7 things you saw in the last 24 hours in the SAW column, one thing you overhead in the last 24 hours in the OVERHEAD box, and in the remaining box, quickly draw something from the SAW column.
For a visual on the box, see the page below from her wonderful, wonderful Syllabus (Drawn & Quarterly, 2014)
