This book could not have been written without the immense patience, generosity and openness of many remarkable investors who shared their intuitions and experiences with me. In some cases we were together for days. Others spoke with me countless times over many years. They gladly welcomed me into their homes and offices, allowed me to travel with them, spoke candidly about their disasters and challenges and, in one unforgettable episode, even hypnotized me in an attempt to reprogram my subconscious mind. I am deeply grateful to all of these investors who shared with me the most valuable lessons they had learned about how to invest wisely, how to think logically, how to recover from adversity and how to increase your chances of having a happy and fulfilling life. There is a long list of exceptionally intuitive investors whose thinking has greatly enriched this book. In particular I would like to thank Charlie Munger, Ed Thorpe, Howard Marks, Joel Greenblatt, Bill Miller, Mohnish Pabrai, Tom Gainer, Guy Speer, Fred Martin, Ken Shubinstein, Matthew McLennan, Jeffrey Gadlak, Francis Chow, Thyra Gerhusen, Thomas Russo, Chuck Ecker, Lai Lu, Peter Lynch, Pat Dorsey, Michael Price, Mason Hawkins, Bill Ackman, Jeff Winick, Mario Babelli, Laura Geritz, Brian McMahon, Henry Ellenbogen, Donald Yacktman, Bill Nygren, Paul Lountzis, Jason Karp, Will Denoff, Fran?oise Rochon, John Spires, Joel Tillingast, Cass Zachariah, Nick Sleep, Paul Isaacs, Mike Jota, Paul Yablon, Whitney Tilson, Fran?oise-Marie Woycik, Sarah Ketterer, Christopher Davis, Ramdev Agrawal, Arnold van den Berg, Mariko Gordon, and Jean-Marie Eveillard.
