Without hard work, nothing grows but weeds.

Do not weep do not wax indignant. Understand.

If you've got a talent, protect it.

Always desire to learn something useful.

Know or listen to those who know.

Quality is not an act, it is a habit.

The most effective way to do it, is to do it.

Never complain and never explain.
