Time

To realize the value of ONE YEAR
ask the student who has failed a class.

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,
ask the person who won a silver medal in the Olympics.

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