"Mr. Dalio has long been an object of fascination. . . . His new book is more significant than the original list of principles: It is part memoir, part how-to guide. It is a deeply personal story, with Mr. Dalio wading into how he started his firm in 1975, internal conflicts inside the company, and strife early on in his career. The book is both instructive and surprisingly moving. . . . Underneath what may seem like a clinical, emotionless approach is something different and far more poignant: Mr. Dalio is preaching for individuals to have a sense of humility and introspection, an ability to open themselves to appreciate pointed criticism and use it to improve." -The New York Times
