No matter what you may be doing, imagine that it is your chief object in life. Imagine you are not interested in anything else in the world but what you are doing. Do not let your attention get away from the work you are at. Your attention will no doubt be rebellious, but control it and do not let it control you. When once you conquer the rebellious attention you have achieved a greater victory than you can realize at the time. Many times afterwards you will be thankful you have learned to concentrate your closest attention upon the object at hand.Let no day go by without practicing concentrating on some familiar object that is uninteresting. Never choose an interesting object, as it requires less attention. The less interesting it is the better exercise will it be. After a little practice you will find you can center your attention on uninteresting subjects at will.
The person that can concentrate can gain full control over his body and mind and be the master of his inclinations; not their slave. When you can control yourself you can control others. You can develop a Will that will make you a giant compared with the man that lacks Will Power. Try out your Will Power in different ways until you have it under such control that just as soon as you decide to do a thing you go ahead and do it. Never be satisfied with the "I did fairly well" spirit, but put forward your best efforts. Be satisfied with nothing else. When you have gained this you are the man you were intended to be.
Exercise 7
Concentration Increases the Sense of Smell. When you take a walk, or drive in the country, or pass a flower garden, concentrate on the odor of flowers and plants. See how many different kinds you can detect. Then choose one particular kind and try to sense only this. You will find that this strongly intensifies the sense of smell. This differentiation requires, however, a peculiarly attentive attitude. When sense of smell is being developed, you should not only shut out from the mind every thought but that of odor, but you should also shut out cognizance of every odor save that upon which your mind, for the time, is concentrated.
You call find plenty of opportunity for exercises for developing the sense of smell. When you are out in the air, be on the alert for the different odors. You will find the air laden with all kinds, but let your concentration upon the one selected be such that a scent of its fragrance in after years will vividly recall the circumstances of this exercise.
The object of these exercises is to develop concentrated attention, and you will find that you can, through their practice, control your mind and direct your thoughts just the same as you can your arm.
Exercise 8
Concentration on the Within. Lie down and thoroughly relax your muscles. Concentrate on the beating of your heart. Do not pay any attention to anything else. Think how this great organ is pumping the blood to every part of the body; try to actually picture the blood leaving the great reservoir and going in one stream right down to the toes. Picture another going down the arms to the tips of the fingers. After a little practice you can actually feel the blood passing through your system.
