If you think you can do it, you can.
What you do today can improve all your tomorrows.
Be gentle to all and stern with yourself.
Problems are not stop signs, they are guidelines.
Expect problems and eat them for breakfast.
The secret of getting ahead is getting started.
By failing to prepare, you are preparing to fail.
To be a good loser is to learn how to win.
Quality is not an act, it is a habit.
Be thine own palace, or the world's thy jail.
