I got into the sales line recently. Badly needing advice on how to succeed in it, I have read a couple of sales books. But I don't seem to learn much and was not at all inspired by them. Until, I discovered this book by Frank Bettger. Reading this book, I found Frank a very sincere person, one happy to pass on all the successful sales experiences he had garnered to readers.No doubt about is. This is the best sales book in the world. Any reader will benefit tremendously from it.
