Fortunately there is one method superior to any yet named, which requires no study before its application, and no paraphernalia during it. It consists in simply talking your thoughts as you think them. One who has not tried this can have no idea of its effect. It possesses almost all the advantages of writing. You cannot wander without realizing the fact immediately. It makes your thinking much less vague than if you thought silently, increases your vocabulary, always keeps pace with your ideas, and requires practically no attention. It may be objected that silent thinking itself is put in unspoken words. But this is not true. Part of silent thinking consists of unspoken words, but part of it consists of images, concepts and attitudes which pass through our minds and which we do not take the trouble to name. In silent thinking, too, there are also what appear to be occasional dead stops. All these processes drift into each other indefinably and are unrecognizable. When we talk we realize whether our images or concepts are vague or definite by our ability to name them, and we realize when our thought comes to a “dead stop” by the fact that we miss the sound of our own voice. Another practice can be used with talking. The degree of concentration we give to any subject depends upon the degree of natural interest we take in it. Mind wandering comes because we are also interested in other subjects. No matter how slight our interest in a thing, we would always concentrate on it if we were interested in nothing else. To secure sustained attention, then, we should (1) stimulate or increase interest in problems we want to concentrate on, (2) decrease or remove temporarily any interest in the things we do not want to think about. Men often complain that noises distract their attention. While not impossible, it is inconvenient and unpleasant to shut off our ears. But men are far more distracted by sights than they are by sounds. And they never think of merely shutting their eyes. The next time you attempt to concentrate—silently or by talking—try shutting your eyes and see whether or not you are helped. Talking has one disadvantage—it cannot always be used. To practice it, you must either lock yourself up in your room, or sit alone in a forest or field, or walk along unfrequented streets and by-ways. You can by no means allow any one to hear or see you talking to yourself. If you are caught doing this some asinine idiot is sure to mistake you for one.
