In this 4-minute talk, Arianna Huffington (founder of The Huffington Post) shares a small idea that can awaken much bigger ones: the power of a good night's sleep. Instead of bragging about our sleep deficits, she urges us to sleep our way to increased productivity and happiness -- and smarter decision-making.

Quotes from the talk:

"I was recently having dinner with a guy who bragged that he had only gotten four hours sleep the night before. And I felt like saying to him, "You know what? If you had gotten five, this dinner would have been a lot more interesting."

There is now a kind of sleep deprivation one-upmanship. Especially here in Washington, if you try to make a breakfast date, and you say, "How about eight o'clock?" they're likely to tell you, "Eight o'clock is too late for me, but that's okay, I can get a game of tennis in and do a few conference calls and meet you at eight." And they think that means that they are so incredibly busy and productive, but the truth is they're not."
