A groundbreaking new understanding of happiness to help us build a fuller, more authentic life. We all want a good life. But do the simple, predictable pleasures we call happiness lead to complacency and regret? Does a life of purpose invite narrow or misplaced loyalties? Now, one of our foremost psychologists Shigehiro Oishi proposes a new way to live. Psychological richness is a concept that prioritizes curiosity, exploration and a variety of experiences. These can be as simple as taking a walk, or as complex as moving to a new country, causing a shift in perspective that helps us grow. Weaving his own story with those of people like Steve Jobs, Oliver Sacks and Alison Gopnik, and original research from fields ranging from moral philosophy, literature, culture, neuroscience, personality and psychology, Oishi shows how to deepen and better our existence through psychological richness.
