Will power covers up inability

In the systems of teaching generally accepted today emphasis is placed on achieving a certain aim at any price, without regard for the amount of disorganized and diffused effort that has gone into it. So long as organs of thought, feeling, and control are not organized for action that is coordinated, continuous, smooth and efficient - and therefore also pleasant - we are involving parts of the body indiscriminately, even if they are in no way required for this action or even interfere with it. One result is that we quite often perform an action and its opposite at the same time. Only mental effort can then make the part that is directed toward the goal overcome the other parts of the body operating to frustrate it. In this way, unfortunately, will power may tend to cover up an inability to carry out the action properly. The right way is to learn to eliminate the efforts opposing the goal and to employ will power only when a superhuman effort is required.
