This is one of the best book I have read about the negotiation skills. When I started this book, a person from FBI what else he can teach us. Then after reading, it's going like a thriller story on each chapter. How he has handled different kidnapping cases and what technique work on when. This book not only help you to successfully complete the business deals, this would also help you to have better relationship with your family and relationship in communicating with more effective way.
In simple words, how we frame the sentence and tone or voice matter most cases. Let's go and buy this book now. It helped a lot and I have asked our Sales Team to read this book once.
