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 mystery. Today is a gift. Your past will not change, and your future concerns may never come. Many people spend a great deal of time and energy thinking about past problems and future concerns while the present is passing them by. Remember the here and now is a gift, which is why they call it the present .
