This book is based on the most popular negotiating class undertook by Diamond in Wharton Business School, and has summarized a set of concrete, practical, applicable negotiating skills. Professor Diamond once claimed whether people required the shop manager to lower 100 yuan or demanded the manufacturer to lower 10000 yuan, they would apply the same negotiating tools. That means once you have learned negotiating skills, you could achieve more in your life. The traditional ideas are challenged on nearly every page of this book. The key to get more is to choose the right skill when negotiating and know to adapt, and try to learn the intention of your negotiating partner.
