Positive psychology is the scientific study of what makes life most worth living (Peterson, 2008). It emphasizes understanding what makes people happy, how individuals flourish, and achieving one's best self. Martin Seligman is considered the father of positive psychology. He developed the PERMA model of well-being which includes positive emotion, engagement, positive relationships, meaning and achievement. Seligman also described three dimensions of happiness that can be cultivated: the pleasant life, the good life, and the meaningful life.
