"In Principle"

The book is divided into three parts. The first part is the personal autobiography of the author Ray Dalio, telling the story of his journey from a middle-class American family to creating the world's largest hedge fund, Bridgewater Associates. The second and third parts describe Ray Dalio's experience and principles in life and work over the years in the form of methodology. With Dalio's various real cases over the years, it is not only a guidebook for financial management, but also a philosophical book with in-depth reflections on life.
