* Study things from as many points of view as possible, and try to understand as many models of thought as you can. This way, you can better understand the behavior of other people, and how people can think in ways that seem incomprehensible to you. If an atheist, talk to religious people until you understand them well enough not to consider them silly; if religious, talk to atheists until you understand them in the same way….
