Never complain and never explain.
Without hard work, nothing grows but weeds.
Know or listen to those who know.
Always desire to learn something useful.
If you've got a talent, protect it.
Do not weep do not wax indignant. Understand.
Go for it now. The future is promised to no one.
Quality is not an act, it is a habit.
Problems are not stop signs, they are guidelines.
Be gentle to all and stern with yourself.
Under capitalism each individual engages in economic planning.
