Ray Dalio was someone who I was unfamiliar with. I was searching for a book that was both business focused and would also teach me a thing or two about life. Principles fit the bill quite well. In the first half of this book you learn all about the life of Ray Dalio and acts as a memoir to set the stage for all of his wisdom which comes in the second half. Although he is well known in financial circles, I was totally unaware of this guy so the intro was welcome despite being a bit lengthy. Having this context the reader gets way more out of the principles touched on in the later chapters. Dalio’s experience in the financial field is fascinating especially dealing with commodities, but what I found most impactful was his view on things over a long period of time whether it be months to years. When I started out investing my strategy was to look for quick incremental gains, and not thinking long term so it was good to learn from someone who has been playing the long game for years. Then on the personal side he has a lot to say about maturity like taking time to address all of the options before taking the first thing that comes. Words to live by, and something I again have not done enough of. Pick this up if you need some wisdom in your life.
