To realize the value of ONE MONTH
ask a mother who gave birth to a premature baby.

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.

To realize the value of ONE MINUTE
ask a person who missed the train.

To realize the value  of ONE SECOND 
ask a person who just avoided an accident.

To realize the value of ONE MILLISECOND

Treasure every moment that you have!
Yesterday is history, 
Tomorrow is mystery.
Today is a gift.
That's why it's called the present!
