Quality is not an act, it is a habit.

Never complain and never explain.

What you do today can improve all your tomorrows.

Do not weep do not wax indignant. Understand.

Always desire to learn something useful.

If you think you can do it, you can.

If you've got a talent, protect it.

If you're going through hell, keep going.

Be gentle to all and stern with yourself.
