I've kept journals at times but then at some point my routine gets interrupted, or my reason for journaling takes a backseat. I have sometimes journaled to work through a problem, or kept a sketchbook in my nightstand to jot down ideas that won't let me sleep or dreams that I want to capture as soon as I wake up. I've tried occasionally doing a daily writing exercise a la The Artist's Way. But can't say I've been consistent.

Right now I'm keeping a food journal, because I'm curious to track if I'm consistently getting a good variety of foods and balanced nutrition.
