Enjoy the moment

When we have something, we dont understand the significance of that possesion, once we lose that we contemplate a lot about it !!! May be that might be human nature,but those who have achieved something in life would have done it little differently - Yes they would have enjoyed the possesion when they got it !!!! To put it simply "Enjoy the Moment" - cos we dont know whether we will be there to enjoy the other day ???? Kal Ho Na Ho..........
