If you think you can do it, you can.

It's always too early to quit.

I can, therefore I am.

To be a good loser is to learn how to win.

Do not weep do not wax indignant. Understand.

The wise does at once what the fool does at last.

Never complain and never explain.

Quality is not an act, it is a habit.

Expect problems and eat them for breakfast.
