People often say, "Time is money," But in fact time is more valuable than money. Why? Because when money is spent, we can earn it back. However, when time is lost, it will never return. This is the reason why we must value time. 　　The time we have is limited. Every second is precious. We should make full use of our time. But there are a lot of people who do not know the importance of time. They kill away their time chatting, smoking, drinking or gambling, They do not realize that wasting time is simply wasting their valuable life. 　　In a word, we should get into the good habit of saving time. Do not leave what can be done today until tomorrow. Laziness will not only bring us failure but also lead us to the road of poverty.
