It is known to all that nothing is much precious than time. A famous saying goes, “Time is money”, which shows that time is invaluable. When time is gone, it will never return back. But it is pity that some people didn’t make full use of their time. They spend a lot of time sleep, chatting or playing computer game. They don’t realize that wasting time is actual equal to killing themselves. We always regret not having made great achievements. However, to be successful, they should first form the habit of being on time. Don’t put down what can be done today until tomorrow. Being lazy will eventually lead to failure.
