Peter Thiel was one of the co-founders of PayPal and also member of the PayPal mafia, I would say this book is more of his thoughts about how the Silicon Valley works than a know-how book. Anyway I recommended to to anyone interested in business management and technology.
This book was on my reading list for a long time, many times had been recommended to me. I did enjoyed reading it, Mr. Feynman had definitely an interesting life. Many interesting stories from long time ago.
