Time flies like an arrow before we realize it .It is known that nothing is more precious than time. The good old proverb "time is money" reminds us that time is valuable. When time goes by, it will never return. However, it is a pity that some people don't make full use of their time .They spend a lot of time in sleeping, chatting, playing computer games or other unmeaning matters. . They don't realize that wasting time is actually equal to killing themselves. They always regret not having made great achievements. One of the reasons may be they do not make good use of time. Therefore, in order to be successful, they should first get into the habit of being on time. It’s a sign of cherishing time. Don't put off what can be done today until tomorrow. Being lazy will eventually lead to failure. Don't wait, because you don't know how long it will take when you put off your plan.
