Remember where you came from.

Enjoy your time in public service. It may well be one of the most interesting and challenging times of your life.

The price of being close to the President is delivering bad news. You fail him if you don't tell him the truth. Others won't do it.

When you're skiing, if you're not falling you're not trying.

If you are not criticized, you may not be doing much.
