Here are some classic "sales/life" books to get you started.
"How to Win Friends and Influence People"- Dale Carnegie. I would actually recommend buying on CD and sticking it in your car, and listenting to it until your CD player melts the disk from over playing.
"The Pshychology of Selling"- Brian Tracy "Mastering the Art of Selling"- Tom Hopkins "Zig Zigler's Secrets of Closing the Sale"- Zig Zigler "The Greatest Salesman in the World" - Og Mandino
