The dog that trots about finds a bone.
Be gentle to all and stern with yourself.
To be a good loser is to learn how to win.
Always desire to learn something useful.
If you're going through hell, keep going.
Know or listen to those who know.
Never complain and never explain.
Only the educated are free.
Wherever you are - be all there.
Be kind whenever possible. It is always possible.
