As a famous saying goes, time is money, which shows the important of time. Time is valuable but limited. When time is gone, they will never come back.

How a pity it is that many of us make poor use of time. We spend much time play games and chatting online. We don’t realize wasting time are equal to a waste of our life. As the result, we will regret having achieved little one day. However, we should get rid the habit of wasting time. Do not put off that what can be done today until tomorrow. Laziness will not only brought us failure, but also lead us to poverty.
