Little Red Book of Selling
12.5 Principals of Sales Greatness by Jeffrey Gitomer
This guy is great! I’ve been reading his column in the South Florida Business Journal for years.
Required reading for anyone in sales. I also recommend THE SALES BIBLE and and the Little Black Book of Connections.
You should read all these books if you are in sales, marketing, own a business, or manage a sales team. Everyone in the company is a salesperson one way or another.
