Internationally esteemed psychologist Seligman has been on the cutting edge of psychological research for more than two decades, pioneering a science that improves people’s lives. Now he has written his most life-changing book yet: Flourish, a new theory of satisfaction and purpose that will electrify his already massive audience. Building on his game-changing work on optimism, motivation, and character, here is how to get life right.

In a fascinating evolution of thought, Flourish refines what Positive Psychology is all about: Well-Being. And the four pillars of Well-Being—positive emotions, relationships, accomplishment, meaning and purpose—the greatest is meaning and purpose. Flourish’s thought-provoking narrative supports its arguments in inspiring stories of Positive Psychology in action, including: in the U.S. Army to improve soldiers’ emotional resilience during and after service; in innovative schools that educate and motivate; and in corporations to improve performance and goal-setting. With its interactive exercises that help listeners explore their own attitudes and aims, Flourish is a watershed in the understanding of happiness as well as a tool for getting the most out of life.
