“Significant...The book is both instructive and surprisingly moving.” —The New York Times

Ray Dalio, one of the world’s most successful investors and entrepreneurs, shares the unconventional principles that he’s developed, refined, and used over the past forty years to create unique results in both life and business—and which any person or organization can adopt to help achieve their goals.

In 1975, Ray Dalio founded an investment firm, Bridgewater Associates, out of his two-bedroom 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. Dalio himself has been named to Time magazine’s list of the 100 most influential people in the world. Along the way, Dalio discovered a set of unique principles that have led to Bridgewater’s exceptionally effective culture, which he describes as “an idea meritocracy that strives to achieve meaningful work and meaningful relationships through radical transparency.” It is these principles, and not anything special about Dalio—who grew up an ordinary kid in a middle-class Long Island neighborhood—that he believes are the reason behind his success.

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. He also describes the innovative tools the firm uses to bring an idea meritocracy to life, such as creating “baseball cards” for all employees that distill their strengths and weaknesses, and employing computerized decision-making systems to make believability-weighted decisions. While the book brims with novel ideas for organizations and institutions, Principles also offers a clear, straightforward approach to decision-making that Dalio believes anyone can apply, no matter what they’re seeking to achieve.

Here, from a man who has been called both “the Steve Jobs of investing” and “the philosopher king of the financial universe” (CIO magazine), is a rare opportunity to gain proven advice unlike anything you’ll find in the conventional business press.

    Blueprint of a disciplined life filled with excitement and Joy… if followed with action.
  • Very repetitive

    By Jdjxiekwmsmsmmsmsm
    This could have easily been shortened to 1/3 of the current volume. The author repeats himself a lot. A lot of the principles are essentially identical. I was expecting more focus on investing and the principles around that. After all, the guy is a famous big shot hedge fund manager. That was barely touched on. The book started well with personal stories but it slowly disintegrated into just what seems to be a barely organized dump from his diary. I assume the author just got tired after writing page 200. Overall, not a read I would recommend. It feels like a waste of my time but I’m almost at the end and I want to get it in my library of finished books.
  • Great Read

    By Aries7@Life
    Took me a while, but well worth the time to finish it. It is both reflective and instinctive. You will almost have to internalise the idea meritocracy concept and radical truth wisdom behind it. You cannot just read the book, you have to feel it, live it to realise how powerful it’s meaning. Thank you Ray.
  • A must read!

  • Principles 👍🏻👍🏻

    By barrett.davis
    I would recommend this book to anybody who is willing to look within themselves wanting to improve. Principles changed how I viewed leadership and taught me about meritocracy. The thing I love most is principles is that it challenges the way I view my own leadership and accountability. Great great book.
