" A central purpose serves to integrate all the other concerns of a man’s life. It establishes the hierarchy, the relative importance, of his values, it saves him from pointless inner conflicts, it permits him to enjoy life on a wide scale and to carry that enjoyment into any area open to his mind; whereas a man without a purpose is lost in chaos. He does not know what his values are. He does not know how to judge. He cannot tell what is or is not important to him, and, therefore, he drifts helplessly at the mercy of any chance stimulus or any whim of the moment. He can enjoy nothing. He spends his life searching for some value which he will never find. "
