The banker who begins at the bottom - and that is where every banker should begin, whether his social position is at the beginning or the end of an ancestral line - should systematize routine work into habit, thereby simplifying physical movements, diminishing fatigue and assuring speed and accuracy. Uniform and continued practice will create well-beaten channels of thought, so that a minimum of mental suggestion will cause the automatic performance of a mountain of detail, with the nervous system as an ally and not an enemy. The only danger in thus maximizing the physical and minimizing the mental is that intellectuality may sometimes become obscure. The beginner in banking should master routine, but should not let routine master him. In accordance with such conception of routine work, every bank man, no matter what his position, will find it convenient occasionally to use the adding machine. The messengers in preparing their own runs, and in helping with the morning work in the mail or transit department, will find it indispensable to run an adding machine with rapidity and accuracy. In order to secure this rapidity with accuracy, beginners should learn the right method of running such machines from the very start of their training.
