What the new psychology does here is to unify what we have known. We say not the performance of an act alone will establish a habit; not the repetition alone will establish it; not the subsequent satisfaction alone. All of these factors must take part, and they must take part in association. The feeling must accompany the act. It is not sufficient that Richard be assured that some time in the vague future he will derive deep satisfaction from being master of the scales; he must somehow be made to feel a present concern either in what he is doing, or a real interest in the outcome. The time that is to elapse between the beginning of his "practice" and the satisfaction he is to receive must not be beyond the child's power to appreciate. In our actual dealing with children our experience leads us to make use of these principles, often without realizing all that is implied. For example, when the young child by your side shows signs of weariness, and you still have some distance to go, you try to stimulate his interest by telling him of the good things to come at journey's end. If this does not serve your purpose, you draw his attention to the bird on the tree only a hundred feet away, or you challenge him to race with you to the next telegraph post. And if you challenge him to such a race, you are sensible enough to let him win it, for you know very well that nothing will discourage him so much as defeat--that is, the unpleasant feeling of failure; and you know that nothing will stimulate him quite as much as the satisfaction of defeating you. In other words, you set before him one goal after another, each but a small fraction of the main journey, and each within the appreciation of the child, and each offering a satisfactory conclusion that is readily and eagerly seized as _worth striving for_, here and now. Now it may be asked, what discipline is there in doing always what brings satisfaction? How can the children ever learn to do the disagreeable but necessary tasks that make up so large a part of every-day living? Where will they ever learn that some things must be done, not because we like to do them, but because it is our duty to do them? And these are indeed serious questions. There are two sets of answers. One of them consists of the results actually achieved in dealing with children from the new point of view. The other is a challenge to make clear just what we mean by discipline and task and duty.
