Drive: The Surprising Truth About What Motivates Us
Daniel H. Pink
 In his book Daniel Pink has made a 140-character summary of what the book is about, in the style of Twitter. :"Carrots & Sticks are so last Century. Drive says for 21st century work, we need to upgrade to autonomy, mastery and purpose." Another summary was done by RSAnimate, a ten minute video animation adapted from Dan Pink's talk at the RSA.
