It is a good idea when time is limited to read only a short sentence and then try to write it down word for word. When you are able to do this, read two or more sentences and treat similarly. The practice will produce very good results if you keep it up until the habit is fixed.
If you will just utilize your spare time in practicing exercises like those suggested you can gain wonderful powers of concentration. You will find that in order to remember every word in a sentence you must keep out every thought but that which you wish to remember, and this power of inhibition alone will more than compensate for the trouble of the exercise. Of course, success in all of the above depends largely upon cultivating, through the closest concentration, the power to image or picture what you read; upon the power, as one writer expresses it, of letting the mountains of which we hear loom before us and the rivers of which we read roll at our feet.
Exercise 17
Concentration Overcomes Bad Habits. If you have a habit that you want to get rid of, shut your eyes and imagine that your real self is standing before you. Now try the power of affirmation; say to yourself, "You are not a weakling; you can stop this habit if you want to. This habit is bad and you want to break it." Just imagine that you are some one else giving this advice. This is very valuable practice. You, in time, see yourself as others see you. The habit loses its power over you and you are free.
If you will just form the mental image of controlling yourself as another person might, you will take a delight in breaking bad habits. I have known a number of men to break themselves of drinking in this way.
Exercise 18
Watch Concentration. Sit in a chair and place a clock with a second hand on the table. Follow the second hand with your eyes as it goes around. Keep this up for five minutes, thinking of nothing else but the second hand, This is a very good exercise when you only have a few minutes to spare, if you are able to keep every other thought in the stream of consciousness subordinate to it. As there is little that is particularly interesting about the second hand, it is hard to do this, but in the extra effort of will power required to make it successful lies its value. Always try to keep as still as possible during these exercises.
In this way you can gain control over nerves and this quieting effect is very good for them.
Exercise 19
Faith Concentration. A belief in the power to concentrate is of course very important. I purposely did not put this exercise in the beginning where it naturally belongs because I wanted you to know that you could learn to concentrate. If you have practiced the above exercises you have now developed this concentration power to a considerable extent and therefore you have faith in the power of concentration, but you can still become a much stronger believer in it.
