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

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.

There, my review is almost as long as the first chapter of the book. I can't imagine what possible excuse you can dream up for not buying this book for every single person you work with, right now."

A must read for every entrepreneur.”

Each chapter is 2-5 pages long and delivers their tactics and principles fat-free, without fluff. Just like their business models."
