There is a nursery rhyme which came from England to the United States: 
" A dillar, a dollar, a ten o' clock scholar . You used to come at 10 o' clock and now you come at noon. " If you fit that description, then you are the opposite of a punctual person. Punctuality means being on time and in the proper place at the right time.
I am always punctual for my classes, appointments, or religious services. When I visit a home, I am not always as punctual. However, if I come late to my classes or miss the correct time or place, my students lose confidence in me, and believe that they may also come late. If I am not punctual, my students don't think that they have to turn assignments in on time either. If I visit a home and I am only a few minutes late, my host perhaps will not mind. However, if I come quite late, the already cooked meal may get cold and others may be put at a disadvantage.
We should cultivate the habit of punctuality in all of our activities. Then others can count on us to keep our commitments, and we can gain their respect as one whom they can trust on other matters. Also, if we are punctual with our commitments and assignments, others who have completed their tasks on time will be glad to work with us in the future.
