Principles: Life and Work by Ray Dalio

Principles: Life and Work by Ray Dalio presents the unconventional principles he says he has developed, refined and used over forty years to shape outcomes in both life and business. Described by The New York Times as “significant” and “both instructive and surprisingly moving”, the book has also been listed as a #1 New York Times bestseller, with 5 million copies sold.

Dalio founded Bridgewater Associates in 1975 from his two-bedroom apartment in New York City. Forty years later, Bridgewater is described as having made more money for its clients than any other hedge fund in history and, according to Fortune magazine, grown into the fifth most important private company in the United States. Dalio has also been named to Time magazine’s list of the 100 most influential people in the world, and he attributes his success to the principles behind Bridgewater’s culture of “idea meritocracy” and “radical transparency”.

Synopsis

Dalio argues that life, management, economics and investing can be systemised into rules and understood like machines. He shares hundreds of practical lessons built around “radical truth” and “radical transparency”, including approaches to decision-making, tackling challenges and building teams.

The book also describes tools used at Bridgewater to support an idea meritocracy, such as employee “baseball cards” that summarise strengths and weaknesses, and computerised systems designed to make believability-weighted decisions. Dalio presents these ideas alongside a clear approach to decision-making that he believes can be applied to a wide range of goals.
