And then he foresees the day as well as he can. His experience teaches him where he will have difficulty, and he administers to his brain the lessons of which it will have most need. He carefully looks the machine over, and arranges it specially for the sort of road which he knows that it will have to traverse. And especially he readjusts his point of view, for his point of view is continually getting wrong. He is continually seeing worries where he ought to see material. He may notice, for instance, a patch on the back of his head, and he wonders whether it is the result of age or of disease, or whether it has always been there. And his wife tells him he must call at the chemist's and satisfy himself at once. Frightful nuisance! Age! The endless trouble of a capillary complaint! Calling at the chemist's will make him late at the office! etc. etc. But then his skilled, efficient brain intervenes: 'What peculiarly interesting material this mean and petty circumstance yields for the practice of philosophy and right living!' And again: 'Is _this_ to ruffle you, O my soul? Will it serve any end whatever that I should buzz nervously round this circumstance instead of attending to my usual business?' I give this as an example of the necessity of adjusting the point of view, and of the manner in which a brain habituated by suitable concentration to correct thinking will come to the rescue in unexpected contingencies. Naturally it will work with greater certainty in the manipulation of difficulties that are expected, that can be 'seen coming '; and preparation for the expected is, fortunately, preparation for the unexpected. The man who commences his day by a steady contemplation of the dangers which the next sixteen hours are likely to furnish, and by arming himself specially against those dangers, has thereby armed himself, though to a less extent, against dangers which he did not dream of. But the routine must be fairly elastic. It may be necessary to commence several days in succession--for a week or for months, even--with disciplining the brain in one particular detail, to the temporary neglect of other matters. It is astonishing how you can weed every inch of a garden path and keep it in the most meticulous order, and then one morning find in the very middle of it a lusty, full-grown plant whose roots are positively mortised in granite! All gardeners are familiar with such discoveries.
