Very entertaining book.  Feynman was famous for taking a fresh, original approach in physics; he was always re-inventing the ideas for himself by thinking them through profoundly, starting from fundamentals.  He made great contributions and won the Nobel Prize in Physics.  This book is not so much about physics, instead some humorous stories and adventures, which show his fresh, original approach to life.  I admire his enthusiasm, his love for adventure, his sparkling personality, his honesty and the clarity of his thought, and his disdain for pretense.  The anecdotes give much insight into why Feynman was such a great physicist.  If you want learn about physics, with his original approach on full display, his best two books are the famous "Feynman Lectures on Physics" (undergraduate courses at Caltech) and "QED, the Strange Theory of Light and Matter".
