His non-physics books, like 'Surely You’re Joking, Mr. Feynman' are great."

Boyan Slat: "A delightful collection of stories by one of the most original physicists. Feynman finds a level of joy in mundane situations most people can only aspire to."

Seth Godin: "This book will make you uncomfortable. Depending on what you do all day, it might make you extremely uncomfortable. That's a very good thing, because you deserve it. We all do.

Jason and David have broken all the rules and won. Again and again they've demonstrated that the regular way isn't necessarily the right way. They just don't say it, they do it. And they do it better than just about anyone has any right to expect.

This book is short, fast, sharp and ready to make a difference. It takes no prisoners, spares no quarter, and gives you no place to hide, all at the same time.
