Over the years, the name "Zig Ziglar" has become synonymous with "sales". He's truly a professional with the wonderfully positive mental attitude to overcome practically any obstacle. Clearly, Ziglar has a great deal of charisma and charm, but what really made him an icon is his ability to provide his customers with true "value". That's the mark of a successful salesperson; they are able to deliver much more than a product or service. They deliver "value".
Philosophically, this book ties in perfectly with a couple of other great books I've recently read---Endless Referrals, Third Edition & The Go-Giver: A Little Story About a Powerful Business Idea, both written by Bob Burg. Burg, like Ziglar, is an eternal optimist and a true giver of "value".
If you're in the business of selling anything; and really, who isn't; grab this Ziglar gem, and add the other two to your sales collection. You can't miss.
