Other engineers plan great mechanical projects. He plans and executes great commercial projects. The results of his work are no less magic than the results of theirs. The ability of the civil engineer is tested by his power to remove the impediments and bridge the chasms that lie in his way. The ability of the commercial engineer is tested in the same way. He must penetrate the hills of prejudice and bridge the chasms of unconcern. There are some enterprises which may at times succeed by force of chance or circumstance. The only sustained and creditable success, however, must come from intelligent promotion. One has little ground for satisfaction over a mere random success. It is real achievement that brings enduring satisfaction. It takes somewhat more than merely mental power, however, to plan and execute great commercial enterprises. The promoter must not only have a good mind, but it must also be of the affirmative type. Only the constructive thinker makes the great general, the great leader, or the great engineer. There is as much of a place for originality in business as in any other field one could enter. It is sometimes avoided on the ground that it is prosaic and humdrum. It is not so for the person who senses its opportunity and enjoys the process of working out its larger possibilities. It offers a practically unlimited opportunity for the building of one’s powers into the fabric of an altogether necessary social institution. Considered from this point of view, business is infinitely more than mere exploitation. Many have conceived the idea that it is nothing more because a great many selfish and misguided men have never really tried to make anything more of it. Fundamentally, however, business is a form of public service. The market place was one of the earliest developments in our social scheme. Theoretically it is a means for the exchange of values to the mutual advantage of the parties to a transaction. The assumption of any person who enters a legitimate line of trade is that he has an article needed by the public. It follows that the degree of his public service is commensurate with the wideness of the sale of his product. In taking steps, then, to create a legitimate demand for whatever he has to sell, one does not need to hesitate on the ground that it reduces his work to the level of mere exploitation. If he is in business as a public servant, then the larger the service he can render the better it is, both for him and for his patrons. The service of his patrons and his own success are commensurate because they are mutually dependent upon one another. Good business spells more than profit for the business man. It is also a help to the public, and a means of progress in the world.
