The Teachings of Don Juan

Nothing being more important than anything else, a warrior chooses any act, and acts it out as if it mattered to him. His controlled folly makes him say that what he does matters and makes him act as if it did, and yet he knows that it doesn't, so when he fulfills his acts, he retreats in peace, and whether his acts were good or bad, or worked or didn't, is in no way part of his concern.
