The document discusses using visual thinking and drawing pictures on napkins to solve problems. It presents three "legs" or rules of visual thinking: 1) Whoever best describes the problem is most likely to solve it, 2) Problems need to be broken down into bite-sized pieces to avoid being overwhelming, and 3) The more "human" the picture, the more human the response will be. It also discusses using the six ways humans see - who, what, how much, where, when, and why - to fully depict problems visually.
