It's always too early to quit.
Be thine own palace, or the world's thy jail.
Never complain and never explain.
Well done is better than well said.
Quality is not an act, it is a habit.
Be kind whenever possible. It is always possible.
Wherever you are - be all there.
Be gentle to all and stern with yourself.
I can, therefore I am.
You never know what motivates you.
I used to spend every morning in detention at my old school.
