Principles

New York Times Bestseller―Ray Dalio, one of the world’s most successful investors and entrepreneurs, shares the unconventional principles that he’s developed over the past forty years to help achieve success in both life and business—and which any person or organization can adopt to improve their performance. In Principles, Dalio shares what he’s learned over the course of his remarkable career. He argues that life, management, economics, and investing can all be systemized into rules and understood like machines. The book’s hundreds of practical lessons, which are built around his Cornerstones of “radical truth” and “radical transparency,” include Dalio laying out the most effective ways for individuals and organizations to make decisions, approach challenges, and build strong teams.
