On Punctuality

A punctual man is in the habit of doing everything at the proper time and is never late in keeping an appointment.

The unpunctual man, on the other hand, never does what he has to do at the proper time. 1. There is a proverb that says, “Time flies never to be recalled.” This is very true. 2. Time is more valuable than material things. In fact, time is life itself, and the unpunctual man is forever wasting and mismanaging his own valuable assets as well as others'. The unpunctual man is always complaining that he finds no time to answer letters, or to return calls, or to keep appointments promptly. 3. He knows that he can't get through his immense amount of work unless he faithfully keeps every appointment promptly and deals with every piece of work when it has to be attended to.

4._ If a person is invited to a dinner and arrives later than expected, he keeps all the other guests and the host waiting him alone. This is great disrespect.

5. Imagine how it would be if those who are entrusted with 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 his fellow men. And the unpunctual man is a source of annoyance both to others and to himself.
