It must be a surprise to most people, after the demonstration of the power of the will in the preceding chapter, that so many fail to make use of it. Indeed, the majority of mankind are quite unable to realize the store of energy for their health and strength and well-being which is thus readily available, though so often unused or called upon but feebly. The reason why the will is not used more is comparatively easy to understand, however, once its activity in ordinary conditions of humanity is analyzed a little more carefully. The will is unfortunately seldom permitted to act freely. Brakes are put on its energies by mental states of doubt and hesitation, by contrary suggestion, and above all by the dreads which humanity has allowed to fasten {20} themselves on us until now a great many activities are hampered. There is the feeling that many things cannot be done, or may be accomplished only at the cost of so much effort and even hardship that it would be hopeless for any but those who are gifted with extremely strong wills to attempt them. People grow afraid to commit themselves to any purpose lest they should not be able to carry it out. Many feel that they would never be able to stand what others have stood without flinching and are persuaded that if ever they were placed in the position where they had to withstand some of the trials that they have heard of they would inevitably break down under the strain. Just as soon as a human being loses confidence that he or she may be able to accomplish a certain thing, that of itself is enough to make the will ever so much less active than it would otherwise be. It is like breaking a piece of strong string: those who know how wrap it around their fingers, then jerk confidently and the string is broken. Those who fear that they may not be able to break it hesitate lest they should hurt themselves and give a half-hearted twitch which does not break the string; the only thing they succeed {21} in doing is in hurting themselves ever so much more than does the person who really breaks it. After that abortive effort, they feel that they must be different from the others whose fingers were strong enough to break the string, and they hesitate about it and will probably refuse to make the attempt again.
