An important principle of success in all walks of life and in all occupations is a willingness to GO THE EXTRA MILE; which means the rendering of more and better service than that for which one is paid, and giving it in a positive mental attitude.
Search wherever you will for a single sound argument against this principle, and you will not find it; nor will you find a single instance of enduring success which was not attained in part by its application.
The principle is not the creation of man. It is a part of Nature's handiwork, for it is obvious that every living creature below the intelligence of man is forced to apply the principle in order to survive.
Man may disregard the principle if he chooses, but he cannot do so and at the same time enjoy the fruits of enduring success.
Observe how Nature applies this principle in the production of food that grows from the soil, where the farmer is forced to GO THE EXTRA MILE by clearing the land, plowing it, and planting the seed at the right time of the year, for none of which he receives any pay in advance.
But, observe that if he does his work in harmony with Nature's laws, and performs the necessary amount of labor, Nature takes over the job where the farmer's labor ends, germinates the seed he plants and develops it into a crop of food.
And, observe thoughtfully this significant fact: For every grain of wheat or corn he plants in the soil Nature yields him perhaps a hundred grains, thus enabling him to benefit by the law of increasing returns.
