Want to be happy? Arthur C. Brooks, president of the American Enterprise Institute, has read all of the books and studies about what makes us happy — so you don't have to. By marrying ancient wisdom and new data, he says we can identify what brings the most happiness, and the most unhappiness, to the most people. In short, love people, not pleasure. This Aspen Lecture was recorded live at the Aspen Ideas Festival. Check out the Aspen Lectures Compendium on iTunes U.
