As a leader, I am tough on myself and I raise the standard for everybody; however, I am very caring because I want people to excel at what they are doing so that they can aspire to be me in the future.

No crime is so great as daring to excel.

I'd rather spend half an hour in the company of a top carpenter, than three hours in the company of an average brain surgeon.

If you think of standardization as the best that you know today, but which is to be improved tomorrow; you get somewhere.

If a man is called to be a street sweeper, he should sweep streets even as Michelangelo painted, or Beethoven composed music, or Shakespeare wrote poetry. He should sweep streets so well that all the hosts of heaven and earth will pause to say, here lived a great street sweeper who did his job well.

All labor that uplifts humanity has dignity and importance and should be undertaken with painstaking excellence.
