"Epicurus wrote, "We must exercise ourselves in the things which bring happiness, since, if that be present, we have everything, and, if that be absent, all our actions are directed toward attaining it." Contemporary research shows that happy people are more altruistic, more productive, more helpful, more likable, more creative, more resilient, more interested in others, friendlier, and healthier. Happy people make better friends, colleagues, and citizens. I wanted to be one of those people."
