About five years ago, I fainted from exhaustion. I hit my head on my desk. I broke my cheekbone and got four stitches on my right eye. It started me on this journey of rediscovering sleep and balance and integrating my life. I think everyone should stop and reassess their lives before you hit your head on your desk.

I usually start with a big question, such as whether people today are happier than in the past, or why men have dominated women in most human societies. And then I follow the question instead of trying to follow my own answer, even if it means I can't formulate any clear theory.

I have one piece of advice for you: sleep your way to the top.

Fearlessness is the mother of reinvention.

The most effective means for restoring the integrity of our electoral process, and repairing the public's tattered faith in its elected representatives, is through the full public financing of political campigns. It's the mother of all reforms: the one reform that makes all other reforms possible. After all, he who pays the piper calls the tune. If someone's going to own the politicians, it might as well be the American people.

Paul Ryan has become a doormat...And he's become this little person who is following Romney around.

Failure is a stepping stone to success.
