My sketchbook is almost exclusively for my personal doodling, idea generation, and, of course, stress relief! I feel like it’s important to have a space to go to get my ideas out, like when I have a flash of inspiration I record it in my sketchbook. I used to not keep a sketchbook, but I have found that it is really useful and after awhile it can become addicting. I also use my sketchbook to work through any angst I’m having. I tend to make really detailed drawings in my sketchbook as a way of meditating.
