Know or listen to those who know.

If you've got a talent, protect it.

Well done is better than well said.

The wise does at once what the fool does at last.

The dog that trots about finds a bone.

If you're going through hell, keep going.

Do not weep do not wax indignant. Understand.

Never complain and never explain.

Quality is not an act, it is a habit.
