Don't watch the clock; do what it does. Keep going. – Sam Levenson

Do not dwell in the past, do not dream of the future, concentrate the mind on the present moment. – Buddha

If you live long enough, you'll make mistakes. But if you learn from them, you'll be a better person. It's how you handle adversity, not how it affects you. The main thing is never quit, never quit, never quit.- William J. Clinton
