To know oneself, one should assert oneself.
Things do not happen. Things are made to happen.
Never complain and never explain.
Be thine own palace, or the world's thy jail.
Problems are not stop signs, they are guidelines.
Quality is not an act, it is a habit.
It's always too early to quit.
To be a good loser is to learn how to win.
Expect problems and eat them for breakfast.
You never know what motivates you.
I have never won a race, and that is my main disappointment - but you have to be positive.
