Be gentle to all and stern with yourself.
What you do today can improve all your tomorrows.
To be a good loser is to learn how to win.
Always desire to learn something useful.
Only the educated are free.
The wise does at once what the fool does at last.
By failing to prepare, you are preparing to fail.
Quality is not an act, it is a habit.
Never complain and never explain.
The secret of getting ahead is getting started.
