A punctual person is in the habit of doing a thing at the proper time and is never late in keeping an appointment.
　   The unpunctual man，on the one hand，never does what he has to do at the proper time.___There is a proverb saying, “Time flies never to be recalled”. This is true. ____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.. ____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.
____If a person is invited to dinner and arrives later than the appointed time，he keeps all the other guests waiting for him. Usually this will be regarded as a great disrespect to the host and all other guests present.
　   Unpunctuality，moreover，is very harmful when it comes to do one's duty，whether public or private. Imagine how it would be if those who are put in charge of important tasks failed to be at their proper place at the appointed time.____
