“Principles” by Ray Dalio

I am so impressed about how he documented his principles in a 123-page pdf, which is served a bible in his company, Bridgewater Associates, and is later published. His principles cover way beyond investing. This is a must-read book that involves all techniques and insights of living life as a wise man.

An excerpt from the introduction:

Above all else, I want you to think for yourself—to decide 1) what you want, 2) what is true and 3) what to do about it. I want you to do that in a clear-headed thoughtful way, so that you get what you want. I wrote this book to help you do that. I am going to ask only two things of you—1) that you be open-minded and 2) that you honestly answer some questions about what you want, what is true and what you want to do about it. If you do these things, I believe that you will get a lot out of this book. If you can’t do these things, you should reflect on why that is, because you probably have discovered one of your greatest impediments to getting what you want out of life.
