Who does not recognize the modest prototype of this elaborate rigmarole chasing itself through his mind as he walks the street in jaunty mood, and who of us would not surprise and alarm his friends if he should suddenly let go his habitual control, express his every thought and materialize his every passing impulse to action? Who can doubt that the person who has trained himself for years to repress his obsessions is less likely to give way to this form of insanity than one who has never practiced such training? Let us then endeavor to pursue "the even tenor of our way" without giving way to the obsession that we must inflict our feelings upon our associates. We may in this way maintain a mental balance that shall stand us in good stead in time of stress. The autumnal tendency to melancholy is recognized by Thoreau. The characteristic suggestion of this nature-lover is that the melancholic go to the woods and study the _symplocarpus foetidus_ (skunk cabbage), whose English name savors of contempt, but whose courage is such that it is already in the autumn jauntily thrusting forth its buds for the coming year. An admirable reflection for the victim of moods, as for many another, is the old saying in which Abraham Lincoln is said to have taken peculiar comfort, namely, "This also will pass." XV. RECAPITULATORY And found no end in wandering mazes lost. _Paradise Lost_. We have reviewed the various phases of worry and the elements out of which worry is assembled. It has been seen that exaggerated self-consciousness blocks effort through fear of criticism, ridicule or comment. The insistent habit of mind in the worrier has been found to permeate the content of thought, and unfavorably to influence action. The fact has been pointed out that the obsession to do the right thing may be carried so far as to produce querulous doubt and chronic indecision--hence worry. It has been pointed out that over-anxiety on the score of health (hypochondria) aggravates existing symptoms, and itself develops symptoms; that these symptoms in turn increase the solicitude which gave them birth. Attention has been called to the influence of over-anxious and fretful days in precluding the restful state of mind that favors sleep, and to the influence of the loss of sleep upon the anxieties of the following day; in other words, worry prevents sleep, and inability to sleep adds to worry. We have seen that doubts of fitness lead to unfitness, and that the worry of such doubts, combined with futile regrets for the past and forebodings for the future, hamper the mind which should be cleared for present action. The injurious effect upon the nervous system of these faulty mental states has been emphasized, together with their influence as potent underlying causes of so-called nervous prostration, preparing the worrier for breakdown from an amount of work which, if undertaken with tranquil mind, could have been accomplished with comparative ease.
