The dog that trots about finds a bone.
You never know what motivates you.
Be thine own palace, or the world's thy jail.
Quality is not an act, it is a habit.
Never complain and never explain.
Expect problems and eat them for breakfast.
Begin to be now what you will be hereafter.
Know or listen to those who know.
Be kind whenever possible. It is always possible.
Always desire to learn something useful.
I used to spend every morning in detention at my old school.
