I always think there is not enough time. For example, I have just taken a three-day holiday. But when I look back, I just feel that it's only one day. There goes a proverb, "Time is money". Now I want to say, time is more precious than money, because when money is spent, we can earn some more again. However, when time is gone or lost, never will it return.

　　Time goes without being noticed. The time for our study and work is usually limited. So I think we must make full use of our time. But it's a pity that I am always not aware of the importance of time until it's too late.

　　So I think, I should get into the good habit of saving time because wasting time is equal to wasting one's life. Do not put off what can be done today till tomorrow!
