I think everyone at this point at least knows what Sun Tzu’s Art of War is, even if they haven’t read it. It elevates war to an art form and wisdom that can be applied to far more than the obvious battlefield. It lays out rules and guidelines that have been translated into the languages of business, creativity, and more.
Today, pick another field that interests you (and that you hopefully know something about—perhaps your own field of work); we’ll call it X for now. At the top of a sheet of paper, write “The Art of X.” Beneath that, use the rest of the sheet to brainstorm guidelines for this art form. Try to limit each one to a sentence or two, but don’t make an artificial attempt to be pithy or sound wise—keep it natural.
