Though everyone wants to be happier, how many of us can actually define what that means? In his class, "Positive Psychology," one of the most popular courses at Harvard University, Ben-Shahar teaches that happiness isn't as elusive a concept as people think, and can actually be learned; he commits the fundamentals of his course to paper in this primer on getting happy, which he defines as a combination of pleasure (short-term happiness) and meaning (long-term). Divided into three parts, "What is Happiness?", "Happiness Applied" and "Meditations on Happiness," Ben-Shahar provides insight and exercises, prodding reflection in readers ("Do you accept negative emotions as natural?" "Do you see your work as a job, a career, or a calling?") while explicating the relationships among happiness, motivation and goals. Though it sounds simple, Ben-Shahar insists on keen self-awareness and purposeful action to overcome entrenched patterns of despondency and/or disbelief.
