Get rid of any habit you have of twitching or jerking any part of your body. You will find you make many involuntary movements. You can quickly stop any of these by merely centering your attention on the thought, "I will not."
If you are in the habit of letting noises upset you, just exercise control; when the door slams, or something falls, etc., just think of these as exercises in self-control. You will find many exercises like this in your daily routine.
The purpose of the above exercises is to gain control over the involuntary muscular movement, making your actions entirely voluntary. The following exercises are arranged to bring your voluntary muscles under the control of the will, so that your mental forces may control your muscular movements.
Exercise 5
Move your chair up to a table, placing your hands upon it, clenching the fists, keeping the back of the hand on the table, the thumb doubled over the fingers. Now fix your gaze upon the fist for a while, then gradually extend the thumb, keeping your whole attention fixed upon the act, just as if it was a matter of great importance. Then gradually extend your first finger, then your second and so on until you open the rest. Then reverse the process, closing first the last one opened and then the rest, and finally you will have the fist again in the original position with the thumb closed over the finger. Do this exercise with the left hand. Keep up this exercise first with one hand and then the other until you have done it five times with each hand. In a few days you can increase it to ten times.
The chances are that the above exercises will at first make you "tired," but it is important for you to practice these monotonous exercises so you can train your attention. It also gives you control over your muscular movement. The attention, of course, must be kept closely on each movement of the hand; if it is not, you of course lose the value of the exercise.
