This is a terrific book that is worth many, many times the cost to download it. You don't have to work in sales to both enjoy and profit from this material. We ALL need to persuade others, whether it's dealing with a customer, a vendor, a spouse or a child. Garf brings a gentle wisdom and humor to the material that makes it a very easy read, but also a very educational one. Buy this book, read it, and use what it teaches. You'll be glad you did!
