If you think you can do it, you can.

I can, therefore I am.

Be gentle to all and stern with yourself.

If you've got a talent, protect it.

What you do today can improve all your tomorrows.

Well done is better than well said.

Do not weep do not wax indignant. Understand.

Know or listen to those who know.

Quality is not an act, it is a habit.
