Never complain and never explain.
Know or listen to those who know.
Without hard work, nothing grows but weeds.
Always desire to learn something useful.
Be gentle to all and stern with yourself.
The dog that trots about finds a bone.
You never know what motivates you.
If you've got a talent, protect it.
Wherever you are - be all there.
It's always too early to quit.
Marriage, laws, the police, armies and navies are the mark of human incompetence.
We have heeded no wisdom offering guidance.
