“Don Juan assured me that in order to accomplish the feat of making myself miserable I had to work in a most intense fashion, and that it was absurd. I had now realized I could work just the same in making myself complete and strong. ‘The trick is in what one emphasizes,’ he said. ‘We either make ourselves miserable, or we make ourselves strong. The amount of work is the same.'”
