This book is yet another posthumous compilation of Feynman's musings. With each successive book - starting from the wonderful transcriptions of Leighton, Surely You're Joking Mr. Feynman - they have been declining in quality for years. Well, this is a hodgepodge of paper scraps and even raw oral interviews that have been thrown together to exploit just about the last drop of these kinds of things, and I can say that I don't think the process should continue.
There are some amusing things in this book and some interesting details, but there really isn't anything special except for the fact that Feynman enjoys the personality cult associated with a zany physics genius. He was an original character and, in physics, a truly great thinker. But that doesn't make every last little thing that he ever said or scribbled down interesting, except to uncritical devotees who live with the fantasy that everything he said was better than worthwhile. Indeed, if you know about something in great depth he writes (well talks) about, his views appear as superficial as the rest of non-specialists on the subjects. Where he is truly interesting in on physics, mathematics, and science - and the overwhelming majority of what he produced on those subjects is already available.
I would not recommend this book, except as a source of Feynman trivia if that is your bag. Indeed, I had heard most of these things before - either in films about the man or from his earlier writings. As such, that makes this book the crassest attempt to commercially exploit the legacy of this great man yet again. If such a thing were possible, the editor should be ashamed.
