It is possible that a man could live twice as long if he didn't spend the first half of his life acquiring habits that shortens the other half.

I know you won't believe me, but the highest form of Human Excellence is to question oneself and others.

We don't settle for anything less than excellence.

In the first 30 years of your life, you make your habits. For the last 30 years of your life, your habits make you.

Intensity is the price of excellence.

Never say any man is hopeless, because he only represents a character, a bundle of habits, which can be checked by new and better ones. Character is repeated habits, and repeated habits alone can reform character.
