In 1975, Ray Dalio founded an investment firm, Bridgewater Associates, out of his twobedroom apartment in New York City. Forty years later, Bridgewater has made more money for its clients than any other hedge fund in history, and grown into the fifth most important private company in the United States, according to Fortune magazine.

In his new book "Principles", Dalio shares what he’s learned over the course of his remarkable career, arguing 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,” offers a clear, straightforward approach to decisionmaking that Dalio believes anyone can apply, no matter what they’re seeking to achieve.
