The Happiness Hypothesis

WHAT SHOULD I DO, how should I live, and whom should I become? Many of us ask such questions, and, modern life being what it is, we don’t have to go far to find answers. Wisdom is now so cheap and abundant that it floods over us from calendar pages, tea bags, bottle caps, and mass e-mail messages forwarded by well-meaning friends. We are in a way like residents of Jorge Luis Borges’s Library of Babel—an infinite library whose books contain every possible string of letters and, therefore, somewhere an explanation of why the library exists and how to use it. But Borges’s librarians suspect that they will never find that book amid the miles of nonsense.
