One of the hardest obsessions to overcome is the _unduly_ insistent habit of mind regarding orderliness and cleanliness. It is not undue to desire and practice a reasonable degree of these virtues, but when it gives one a "fit" to see a picture slightly off the level, and drives one "wild" to see a speck of dust, it is time to modify the ideal. This is the frame of mind which encourages worry over trifles. If one really wishes to lessen worry he must cultivate a certain degree of tolerance for what does not square with his ideas, even if it does violence to a pet virtue. The careful housekeeper may object that so long as she can regulate her household to her liking, the habit of orderliness, even though extreme, causes her no worry. But it is only the hermit housekeeper who can entirely control her household. And further, the possessor of the over-orderly temperament, whether applied to housekeeping, business, or play (if he ever plays), is bound sooner or later to impinge his ideas of orderliness upon the domain of other peoples' affairs, in which his wishes cannot be paramount. In this event, at least, he will experience a worry only to be allayed by learning to stand something he does not like. Worry about the mental condition is disastrous. The habit should be cultivated of taking the mind for what it is, and using it, wasting no time in vain regrets that it is not nimbler or more profound. Just as the digestion is impeded by solicitude, so the working of the brain is hampered by using the energy in worry which should be devoted directly to the task in hand. Children frequently worry because their memory is poor. It should be explained to them that in ninety-nine cases out of a hundred apparent lack of memory is only lack of attention, and they should be urged to cease distracting the attention by wandering in the fields of idle speculation or in making frantic leaps to surmount imaginary obstacles. It is important for parents of morbidly sensitive and over-scrupulous children, with acute likes and dislikes, to discourage the tendency of the child to become more and more peculiar. Sensitive children are inclined to worry because they think others do not care for them or want them round. If such children can be led to take a bird's-eye view of themselves, they may be made to realize that others crave their society according as they are helpful, entertaining, sympathetic, or tactful, because they instil courage and give comfort. They should be urged, therefore, to cultivate these qualities instead of wasting their energy in tears and recriminations; and they should be encouraged to practice such of these traits as they can master instead of becoming moody in society, or withdrawing to brood in solitude, either of which errors may result in producing on the part of others a genuine dislike. In other words, teach them to avoid enforcing too far their _ego_ on themselves or their environment.
