To know oneself, one should assert oneself.
Either you run the day or the day runs you.
You never know what motivates you.
Never complain and never explain.
Expect problems and eat them for breakfast.
Well done is better than well said.
To be a good loser is to learn how to win.
Things do not happen. Things are made to happen.
The dog that trots about finds a bone.
Be gentle to all and stern with yourself.
Secretary of State Colin Powell, thank you so much, as always, for joining us this morning.
