" You bet it is—and if he doesn’t recognize it, it may turn him into Darth Vader. If the person insists on a certain program, and doesn’t listen to the demands of his own heart, he’s going to risk a schizophrenic crackup. Such a person has put himself off center. He has aligned himself with a program for life, and it’s not the one the body’s interested in at all. The world is full of people who have stopped listening to themselves or have listened only to their neighbors to learn what they ought to do, how they ought to behave, and what the values are that they should be living for. "

― Joseph Campbell , The Power of Myth
