To realize the value of:
1 year- ask one who failed in an examination.
1 month- ask one who has not received salary.
1 week- ask one who stayed in relative home
1 day- ask one who is fasting
1 hour- ask one who is waiting for his lover.
1 min- ask one who had missed a train.
1 sec- ask one who had escaped accident.
Every moment is a treasure. Yesterday is history. Tomorrow is Mystery. But Today is a gift. So we call it PRESENT.
