      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 one hand, never does what he has to do at the proper time. He is always in a hurry

and in the end loses both time and his good name. A lost thing may be found again, but lost time can never be

regained. 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 asset 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. But the

man who really has a great deal to do is very careful of his time and seldom complains of want of it. 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.

     Failure to be punctual in keeping one's appointments is the sign of disrespect towards others. 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. A man who is known to be habitually unpunctual is never trusted by his friends or fellow

men.
