Product description
Review
“Mr. Dalio has long been an object of fascination. . . . His new book is more significant than the original list of principles: It is part memoir, part how-to guide. It is a deeply personal story, with Mr. Dalio wading into how he started his firm in 1975, internal conflicts inside the company, and strife early on in his career. The book is both instructive and surprisingly moving. . . . Underneath what may seem like a clinical, emotionless approach is something different and far more poignant: Mr. Dalio is preaching for individuals to have a sense of humility and introspection, an ability to open themselves to appreciate pointed criticism and use it to improve.”
—The New York Times
“If there was an ‘it’ book for businesses or careers in 2017, it was Ray Dalio’s Principles. The book, weighing in at nearly 600 pages, begins with the author’s own story, including the rise of Bridgewater Associates, Dalio’s highly successful investment firm. Part memoir, part strategic plan, Dalio uses his own history to provide suggestions on attaining success while always stressing the power of individuality and personal goals. This isn’t just a book for the power elite. Dalio’s highly detailed game plan focuses on what he calls ‘radical’ truths and transparencies, and are applicable to the careers of powerful CEOs, ladder-climbing executives, longtime grunts, and fresh-faced rookies.”
—Chicago Tribune
“Ray Dalio has provided me with invaluable guidance and insights that are now available to you in Principles.”
—Bill Gates
“I absolutely loved this book. It’s beautifully written and filled with such wisdom.”
—Arianna Huffington
“I found it to be truly extraordinary. Every page is full of so many principles of distinction and insights—and I love how Ray incorporates his history and his life in such an elegant way.”
—Tony Robbins
“Ray Dalio’s market acumen is legendary, but it was creating and living by a set of principles that allowed him to reach the top. Everyone with goals and dreams can learn from Ray’s approach.”
—Michael Bloomberg
“It’s important and instructive to share what you’ve learned in life with others, and Ray does this in an interesting and provocative way in this compelling work.”
—Jamie Dimon
“I was surprisingly moved by it. I found it to be remarkably engaging. It made me think about life and how we all deal with each other in pretty profound ways. And Mr. Dalio’s own story about how he came to these principles is fascinating.”
—Andrew Ross Sorkin
“The billionaire investor has created the strongest culture I’ve ever seen in an organization—one that prizes radical transparency over politics and meritocracy over democracy. In his long-awaited book, he describes the systems that he has designed to shape meaningful work, meaningful relationships, and the world’s most successful hedge fund.”
—Adam Grant
“I highly, highly recommend this book. It has already changed how I think about making decisions in my life and in my business.”
—Tim Ferriss
“It’s the book I wish I had as a young entrepreneur, stressing over not knowing what I didn’t know. Principles offers a bible to the greatest skill an entrepreneur can have, the ability to Learn How to Learn in any situation. Read it.”
—Mark Cuban
“Principles had a profound positive impact on my leadership style—through living more honestly.”
—Reed Hastings
“Ray brings unique analytic insights about how to think about complex issues. His Principles is a must read. It’s a gift to all of us.”
—Steve Schwarzman
“Among a handful of philosopher-investors known not only for moneymaking prowess but also for their distinctive take on life.”
—The Wall Street Journal
“What makes Dalio compelling is not just his track record but the way he goes about making money, and the rigorous analysis he applies to understanding markets, organizations, the economy, and life.”
—Fortune

- Reviewed in India on 7 June 2025Format: HardcoverVerified PurchaseWords are not enough to write comments you are too late to read this 40 years experience contain diamonds for both personal and professional life. RAY Dalio i am personally very thankful to you sir.
- Reviewed in India on 17 July 2020Format: Kindle EditionVerified PurchaseThe author has done a good job of capturing almost everything that he seems to have encountered and penned down in quite an articulate way. The takeout for me was, "find and follow your own principles, not what others have set forward without even understanding why and what of them". This book has been a year long journey for me and I've quite tried to incorporate this thought and it seemed to have helped resolve a lot of internal conflicts. I guess that is the first step in having a clear mind which can lay down a foundation of meaningful life.
Similarly the key point from the work principles was, radical truthfulness and radical transparency. Tried and tested, it seems THE way to be, and have meaningful relationships. As the author also points out, once you get into this, you don't feel like being in any other way.
Some places the book became too much of a formula kind or say calculated, I personally don't like to live that way. But the author also is mindful of pointing out that that is not the only way to go about it hence being open minded, that's a million dollar suggestion. Be open minded and assertive at the same time. There's so much treasure in this book that I'd want to keep coming back and savour it.
The tone is very much humble hence earning the trust, at the same time it also is a bit too programmatic where it looses the connection.
overall, a great reading experience (since I got to also try it out in life practically while reading, the value is more). Perhaps this is a better way of using this book for good, given it's quite long(not in terms of number of pages but the information it provides), it won't make sense if you just read, learnt the principles, got inspired and forgot unless you put them too use.
- Reviewed in India on 27 May 2025Format: HardcoverVerified PurchaseOne of the finest books I have ever read, and the quality of the paper is exceptional.
- Reviewed in India on 25 March 2024Format: Kindle EditionVerified PurchaseThis book is a Collector’s Delight. A wonderful account to be always kept on the work desk and to be referred for clearing challenges of both life and work. The idea meritocracy definition and how to use it can be written down and kept as a handy tool to fix things. Clear, concise and precise defines this book. Recommended for everyone to read and assimilate.
- Reviewed in India on 13 December 2018Format: HardcoverVerified Purchase1) the book & paper quality: the book quality is fine and value for money
2) the content of the book is really interesting and edifying
There is so much for us to learn and apply.
It's inspiring and eye opener to so many things.
It is detailed and has a lot insights. We might find a lot of reference to other books, which one may use as a suggestion (or references ) and expand their reading horizon. Amazing use of language easy to understand, it's been a while since I have read the book and a lot of Decisions have become more faster to take, a lot of error have been reflected upon and some corrected by me, focuses largely on decision making
Some points I would like to brief from the book:
1) Mainly the power of audacious goals
2) Achievements of all goals through collective decision making
3) avoidance of Emotional hijacking or staying clear from harmful Emotions
4) Letting go the attachment of me knowing the right answers
5) use of clinical objectivity
The journey of Ray Dalio has been explained so transparently and with so much detail.
I can go on.
Highly recommend this read to all entrepreneur, start up, HR guys, stock market investors etc
Drawback:
1) A lengthy read
2) something are repetitive
- Reviewed in India on 3 February 2022Format: HardcoverVerified PurchaseThis book is a very good value for your money. Divided in 3 parts, ray dalio shares story about his origin , his life principles and work principles in this book. This book can be read again and again and each time you get to learn something new. Everything Mr. Dalio shares is very useful and when applied seriously can lead to a sucessful life. This book is a must have in your bookshelf and it will add value to your life forever. It must be read again and again as an instruction manual for life and work.

Cristina DanilaReviewed in the Netherlands on 30 December 2017
5.0 out of 5 stars Best management book I ever read
Format: Kindle EditionVerified PurchaseWell if you are a manager there are a lot of situations that leave you doubtful if you made the right decision or not. Given Ray’s principles it helped me a lot in actually realizing what is correct and not in my management style.
There are so many good chapters and principles but one standing out for me was: create a farm team - the group pf people assessed to be as stand by in case one of the people in the key roles happens to be out in a form or another.
I have seen this situation crippling organizations throughout time and its so easy to do, you just need some pragmatism and clear objectives.
Also create clear structure clear direct lines of reporting - i know its already known but the way Ray explains it ... its just brilliant.
Also the take on conflict resolution and the necessity of disagreement - simply brilliant.
