We spend far too much thought on the weather, a subject that really deserves little attention except by those whose livelihood and safety depend upon it. Suppose a runaway passes the window at which we are sitting, with collar off, handkerchief to our heated brow, squirming to escape our moist and clinging garments, and being generally miserable. We rush out of doors to watch his course, and for the next few minutes we do not know whether it is hot or cold, perspiring less during our exertions, I strongly suspect, than we did while sitting in the chair. At all events, it is obvious that our thoughts played quite as great a part in our discomfort as did the heat of the day. Suppose now, instead of devoting all our attention to the weather we should reason somewhat as follows: As long as I live on this particular planet, I shall be subject perhaps three days out of four, to atmospheric conditions which do not suit me. Is it worth my while to fret during those three days and to make it up by being elated on the fourth? Why not occupy myself with something else and leave the weather for those who have no other resource? Or, as someone has said, why not "make friends with the weather?" If one will cultivate this frame of mind he will be surprised to find that a certain physical relief will follow. In the first place, he will lessen the excessive perspiration which is the invariable accompaniment of fret, and which in its turn produces more discomfort than the heat itself. We have selected, so far, the comparatively unimportant sources of mental discomfort, fret, and worry. The reader who can truthfully say that such annoyances play no part in his mental tribulations may pass them and accept congratulations. The reader who cannot be thus congratulated, but who is impatient to attack the major sources of worry, must be reminded at this point that he must practice on the little worries before he can accomplish anything with the great. The method is the same. The philosophy that will make us content with the weather will do something toward establishing the mental poise which shall enable us to withstand with comparative equanimity the most tragic of misfortunes that may fall to our lot. To draw an example from the more serious disorders, let us consider the hypochondriac, who harbors the insistent thought that he must be always perfectly well, that each of his sensations must conform to his ideal, and that each function must follow regulations imposed by himself. If he can learn to ignore this thought by realizing that an acute illness is preferable to life-long mental captivity; if he can learn to do what others do, and to concentrate his energies on outside affairs which shall displace the question of health; if he can learn to say "What I am _doing_ is more important than how I am _feeling_;" he will have cured his hypochondria.
