From the same author that brought you "Eat, Pray, Love" is this book about creativity. She basically goes through all the possible excuses you might have for not being creative and kicks each one to the curb.
Favourite quote from the book:
"Human beings have been creative beings for a really long time - long enough and consistently enough that it appears to be a totally natural impulse. To put the story in perspective, consider the fact: The earliest evidence of recognizable human art is forty thousand years old. The earliest evidence of human agriculture is only ten thousand years old. Which means that somewhere in our collective evolutionary story, we decided it was way more important to make attractive, superfluous items that it was to learn how to regularly feed ourselves."
