As a value investor, this is one of the most comprehensive books on the minds of greatest investors. Beyond Buffett/Munger, William interviewed many of the greatest investors through decades of hard work and it's available to us in this book. If you want to succeed in life and the market, this is a must-read. My personal best is Nick Sleep's chapter and how living a quality life framed his investment approach. Enjoy it (if you do get a copy)!
