To Sell Is Human: The Surprising Truth About Persuading, Convincing, and Influencing Others, by Daniel H. Pink (paperback)
 
We're all in Sales now

Parents sell their kids on going to bed. Spouses sell their partners on mowing the lawn. We sell our bosses on giving us more money and more time off. And in astonishing numbers we go online to sell ourselves on Facebook, Twitter and online dating profiles.

Relying on science, analysis and his trademark clarity of thought, Daniel Pink shows that sales isn't what it used to be. Then he provides a set of tools, tips, and exercises for succeeding on each new terrain: six new ways to pitch your idea, three ways to understand another's perspective, five frames that can make your message clearer, and much more.
