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.
