The conventional wisdom is often wrong. Crime didn't keep soaring in the 1990s, money alone doesn't win elections, and - surprise - drinking eight glasses of water a day has never actually been shown to do a thing for your health.

We overlook just how large a role we all play--and by 'we' I mean society--in determining who makes it and who doesn't.

Hard work is a prison sentence only if it does not have meaning.

When people in authority want the rest of us to behave, it matters-first and foremost-how they behave.

I've always been baffled by how much we over-rate the statistically insignificant differences that separate competitors at the top end of the distribution.

Change your mind about something significant every day.
