Thus the nurse, knowing the laws of attention, can keep herself alert to divert and direct her patient's thought to wholesome interests. Knowing the possibility of thought substitution, she can open up new channels of thinking. Knowing the power of the will to assist in health bringing and health keeping, she can sometimes stimulate long-dormant determination. Let her beware, however, of making the convalescent too dependent upon help from without, but prick his pride to gradually increasing doing for himself. Arouse his reasonable ambition, but let him realize that life must be taken up again a step at a time; and that he _can_ do it. If limitations must be accepted, try to inspire the feeling of pride in accomplishing the utmost possible within a limitation, and an acceptance of the inevitable without bitterness. Attending to the unhappy, the painful, the boring without looking beyond makes life unhappy, painful, and a bore. Not that the nurse should ignore these realities, but she can accept them whole-souledly herself as not the final things, as merely the rocks that can be used to stand upon and get a view of the something better for everybody. When they are thus used by the wholesome mind, facts, the very barest and meanest of them, can be made useful as stepping-stones to the happier facts beyond them. If the nurse can direct or tactfully lead the patient's attention away from himself and his illness, she has found a big reinforcement to his treatment. This question is so vital in the care of patients that it will be discussed at greater length later on. ONE THOUGHT CAN BE REPLACED BY ANOTHER
