Principles in Action is a free app that brings to life Ray Dalio’s best-selling book Principles: Life & Work by guiding you through interactive videos of actual cases of these principles in action at his company Bridgewater Associates. And it provides a lot more.

Principles in Action is being offered free-of-charge in response to strong demand to see Ray’s principles actually operating in the work environment. It includes:

* The complete bestselling book Principles: Life & Work with interactive case studies that show closed-door meetings at Bridgewater.

* The option for you to answer questions about your reactions to these principles shown in action. In future releases, these answers will allow you to compare your reactions to operating this way with those of others to help you learn about yourself.

* A digital “Coach” to help you easily find the appropriate principles for the specific situations you face. It will soon be adapted to help you develop your own principles and collect principles from others.

* Several of Ray’s studies on economics and investing and related subjects.

Principles in Action is also a platform for receiving other principles and tools as they are released, including courses and a tool to help you to develop your own principles. In the future, you’ll also have a chance to take a one-of-a-kind personality assessment which, when combined with your answers to questions in the courses, will give you a detailed picture of what you’re like along with tailored tips to help you achieve your goals in light of what you’re like.

Principles in Action was developed by Ray and Bridgewater for training at Bridgewater Associates. It is based on the principles that produced Bridgewater’s success and were explained in Ray’s book Principles: Life & Work. This book has been recommended by numerous leaders from all walks of life such as Bill Gates, Arianna Huffington, Marc Benioff, Mark Cuban, P. Diddy, Mike Bloomberg, Kevin Systrom, Jamie Dimon, and many others.

Awesome App! Thank you so much Mr. Dalio!!!

Runs smoothly. Great user interface. Most importantly it makes me better. The coach finds answers to life’s problems on a daily basis and teaches you how to better handle challenges. These situations can be saved so you can begin to see how certain principles are more important for you to focus on or find your own answer to. Ray Dalio’s commitment to giving back later in life is actualized in this app by helping us all make better decisions each day. In addition he also provides access to his extensive writing on economic theory in his perspective which is also extremely insightful.

Makes Material Convenient

This really makes digesting Ray Dalio’s lessons convenient. The app remembers where you left off in the books (which also contain extra media) you also get case studies for these principles as if you were a Bridgewater employee.

Honestly, the five star rating really goes to the Coach feature included. I’d say that is the most valuable tool as the app can personally give you principles that would help you gain clarity and resolution to your most pressing problems. Fantastic stuff, I am extremely grateful.



I feel that the concept of principles is extremely important to help one focus on what they really want in life and how to go about it I think anybody Hass to have a set of goals without goals you’re planning to fail I’ve taken an extremely large amount of classes on sales trading and dealing with people I need his help me hone and refine my expertise and not only sales but in everything else in my life I believe this book by Ray Dalio is a fine example of helping others
