Can we really learn to be happy? Yes, we can. Each semester, nearly 1,400 students sign up for Harvard professor Tal Ben-Shahar's life-changing class, "How to Get Happy." Currently it's the hottest course at Harvard, taken by twenty percent of its graduates.In Happier, Professor Ben-Shahar brings the ideas of the Ivory Tower to Main Street, distilling the lessons and exercises from his course into a slim volume of practical wisdom. Grounded in the Positive Psychology movement, based on years of researching the works of scientists, academics, and philosophers, Happier emphasizes the importance of pursuing a life of both pleasure and meaning.
