How will a salesman, for instance, develop interest in his work if he makes more from his ``side lines'' than from the service he renders to the house which pays his expenses? How can the laborer be interested in his work if he believes that by gambling he can make more in an hour than he could by a month's steady work? The successful shoemaker sticks to his last, the successful professional man keeps out of business, and the wise business man resists the temptation to speculate. Occasionally a man may be capable of carrying on diverse lines of business for himself, but the man is certainly a very great exception who can hold his attention to the interests of his employer when he expects to receive greater rewards from other sources.
The power of concentration depends in part upon inheritance and in part upon training.
Some individuals, like an Edison or a Roosevelt, seem to be constructed after the manner of a searchlight. All their energy may be turned in one direction and all the rest of the world disregarded. Others are what we call scatter- <p 127> brained. They are unable to attend completely to any one thing. They respond constantly to stimulation in the environment and to ideas which seem to ``pop up'' in their minds.
Some people can read a book or paper with perfect satisfaction, even though companions around them are talking and laughing. For others, such attempts are farcical.
Many great men are reputed to have had marvelous powers of concentration. When engaged in their work, they became so absorbed in it that distracting thoughts had no access to their minds, and even hunger, sleep, and salutations of friends have frequently been unable to divert the attention from the absorbing topic.
There are persons who cannot really work except in the midst of excitement.
When surrounded by numerous appeals to attention, they get wakened up by resisting these attractions and find superfluous energy adequate to attend to the subject in hand. This is on the same principle that governs the effects of poisonous stimulants. Taken <p 128> into the system, the whole bodily activity is aroused in an attempt to expel the poison. Some of this abnormally awakened energy may be applied to uses other than those intended by nature. Hence some individuals are actually helped in their work at least temporarily by the use of stimulants. Most of the energy is of course required to expel the poison, and hence the method of generating the energy is uneconomical.
The men who find that they can accomplish the most work and concentrate themselves upon it the most perfectly when in the midst of noise and confusion are paying a great price for the increase of energy, available for profitable work. To be dependent on confusion for the necessary stimulation is abnormal and expensive. Rapid exhaustion and a shortened life result. It is a bad habit and nothing more.
Many persons seem able to disregard the common and necessary distractions of office, store, or factory.
Other persons are so constituted that these distractions can never be overcome. Such <p 129> persons cannot hear a message through a telephone when others in the room are talking; they cannot dictate a letter if a third person is within hearing; they cannot add a column of figures when others are talking. Habit and effort may reduce such disability, but in some instances it will never even approximately eliminate it. Such persons may be very efficient employees, and their inability to concentrate in the presence of distractions should be respected. Every business man is careful to locate every piece of machinery where it will work best, but equal care has not been given to locating men where they may work to the greatest advantage.
