Nobody knows what time is like for we cannot see it nor can we touch it. Time is abstract which we can only imagine in our mind.
But we do know that time passes very quickly. Some students however do not know the value of time nor do they know how to make the best use of it for they waste it in going to films playing games and doing other useless things. Why do we go to school early in the morning? Why do trains run so fast? Why do most people prefer taking buses instead of walking? The answer is very simple: we wish to save time because time is precious.
