Arianna Huffington is the co-founder and editor-in-chief of The Huffington Post. In this recent talk for TEDWomen in Washington, she proposes a radically simple solution to success: let's stop bragging about how busy we are and get more sleep.

She argues that it is these outdated, and mostly male, models of working that got us into the current financial mess. If the (mostly) men in charge of the financial institutions had had a good nights sleep, would they have made better decisions? Like many evangelists, she came to this conclusion after the awakening experience (pun intended) of falling asleep from exhaustion at work and breaking her cheek bone when her face hit the desk.

Time for a nap?
