time flies like an arrow before we realize it .it is known that nothing is * precious than time. the good old proverb "time is money" reminds us that time is valuable. when time goes by, it will n*r return. how*r, 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 com*r *s or other unmeaning matters. . they don't realize that wasting time is actually equal to killing themselves. they always regret not having made great achi*ments. one of the reasons may be they do not make good use of time. therefore, in order to be succes*ul, they should first get into the ha*t 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 *ntually lead to failure. don't wait, because you don't know how long it will take when you put off your plan. __
