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)
