This is true. __小题2:__Time is more valuable than material things. In fact,time is life itself. The unpunctual man is for ever wasting and mismanaging his most valuable possessions as well as other's. The unpunctual person is always complaining that he finds no time to answer letters,or return calls or keep appointments promptly.. __小题3:__He knows that he can not get through his huge amount of work unless he faithfully keeps every piece of work when it has to be attended to.
