People often say, “Time is money.” But in fact time is less valuable than money. Why?
Because when money is spent, we can earn them back. However, when time lost, it will never return. This is the reason why we must value time. The time we have is limit. But there are a lot of people who do not know the important of time. They kill time by chatting, drinking or gambling. They didn’t realize that waste time is simply wasting their valuable lives. In the word, we should develop the good habit of saving time. Don’t leave what can be done today till tomorrow. Laziness will not only bring to us failure, and also make us lead a poor life.
