Know or listen to those who know.
Always desire to learn something useful.
The dog that trots about finds a bone.
Be gentle to all and stern with yourself.
Never complain and never explain.
If you're going through hell, keep going.
After a storm comes a calm.
Without hard work, nothing grows but weeds.
If you've got a talent, protect it.
Do not weep do not wax indignant. Understand.
A failure will not appear until a unit has passed final inspection.
