I really enjoyed this book. It is very well written and entertaining. I still respect Dalio, but after reading this book, which I can assure is most probably true, much of the admiration I had for Dalio has disappeared. He made a lot of money, but is a troubled soul and part psychopath. Warren Buffett & Charlie Munger remain the best examples of the investor par excellence. No one is perfect, but Dalio is best served by throwing out his ridiculous "principles" and quietly retiring from public life: no one wants to listen to him pontificating.
