Know or listen to those who know.
By failing to prepare, you are preparing to fail.
Expect problems and eat them for breakfast.
Never complain and never explain.
The dog that trots about finds a bone.
Things do not happen. Things are made to happen.
Wherever you are - be all there.
Always desire to learn something useful.
What you do today can improve all your tomorrows.
Be gentle to all and stern with yourself.
It often takes more courage to change one's opinion than to keep it.
