I use doodling for a variety of reasons: I use it to get clarity around a concept, I use it to relax, I use it to communicate ideas with others and get their refinement of them, I use it to map complex systems for companies, I use it to run innovation games for business, I use it to get insight on something puzzling me. Sunni Brown
