The author does love selling. He does have a true passion for selling, and also for writing books about selling. I think this book really helps understand if you have the basic attributes to be a successful sales man. No quick fix, no magic potion, just fundamental steps. Effective and practical approach.
This book helps you understand (but really understand) if you may be in the big club of sales people, of you are looking at your position as a job, not as a career, if you are really self-motivated.
The author is right when he says that this book is to be read and re-read. Because this is a book to be studied. And implemented.
