It's always too early to quit.
Well done is better than well said.
Who seeks shall find.
Either you run the day or the day runs you.
To be a good loser is to learn how to win.
Expect problems and eat them for breakfast.
Things do not happen. Things are made to happen.
If you think you can do it, you can.
The wise does at once what the fool does at last.
Never complain and never explain.
Dispassionate objectivity is itself a passion, for the real and for the truth.
If you only have a hammer, you tend to see every problem as a nail.
The story of the human race is the story of men and women selling themselves short.
