I try to feed my brain daily with information and ideas from multiple sources on a variety of topics. Partially because my friend Chris Millis propecia ed (author and illustrator as well as acomplia medicine man about town) in a conversation years ago told me part of his secret to good comic strips involved having a vast cross section of potentially useless knowledge.
Much of my success has come from being able to recognize patterns in one area and apply solutions to similar issues from a different area. Physics solves finance problems. Martial arts philosophy solves marketing ideas. Thinking like a five year old solves many issues. So having just more random ideas and knowledge can create answers.
