Aproverb says, “Time is money.” But in my opinions, time is even much valuablethan money. Why? Because when money is spent, we can earn them back, so whentime is wasted, we can never get it back. There is no doubt when time is verylimiting, and even an hour is of great value. We should make full use of timedo useful things. It's a pity that a lot of people didn't appreciate the valueof time. They waste their time doing anything useful. We should form the goodhabit of racing against the time.
