To realize the value of ONE YEAR, ask a student who failed a grade. To realize the value of ONE WEEK, ask the editor of a weekly newspaper. To realize the value of ONE HOUR, ask the lovers who are waiting to meet. And treasure it more because you shared it with someone special, special enough to spend your time. And remember that time waits for no one.
Yesterday is history.
Tomorrow is a mystery. Today is a gift. That's why it's called the present.
