Query: Maybe he was once a good salesman...

He talks about how great he was and for good reason, he's proud. I don't suggest the book however for anyone selling anything other than knives, direct TV in Best Buy, used cars, etc.He talks soo negatively about customers and basically says to pretend to like people and pretend to care. The bottom line is that is no way to sell if you sell something where the customers know what they are doing. If you are in pharmaceutical, medical equipment, college textbook, etc. sales (or anything where the buyer knows more about your product than you do), following this book could ruin your career.Stop Telling, Start Selling a lot better book and shows how to do things the right way.
