Unpunctuality and untidiness are responsible for a great amount of unnecessary worry. The man who is habitually late in the mornings is apt to find his work accumulate to such an extent that by the time he ought to be finishing his day’s work he feels it has become a heavy burden upon his shoulders. And people who keep their desks in an untidy condition lose a vast amount of time, and harass themselves by having to search for things they should have been able to put their fingers on at once. [Sidenote: Stimulants.] Above all, let a man avoid stimulating his flagging brain by means of alcohol, or soothing it by the aid of drugs. Tobacco, however, is--in the writer’s opinion at least--a boon to people of a worrying disposition. If used to excess, especially in the form of cigarettes, it may sap the nervous system, and lead to more worry than it is likely to prevent. Taken in moderation, and in its healthiest form, that of a pipe, it often proves of great benefit to tired nerves. [Sidenote: Leisure time.] It is of the utmost importance for people who are subject to worry to pay every attention to the way in which they spend their leisure time. It is even more important in their case than in that of people who work too hard. [Sidenote: Overwork compared with worry.] The effect of overwork is to cause fatigue. The mind has been kept too long in a certain groove, until it has become wearied from sheer exhaustion. Certain parts of the brain or the body are tired out for the time being. Such persons need recreation pure and simple. A pleasant game or a light novel is the best remedy for their fatigue, taking the mind out of the groove in which it has been confined. The effect of worry, on the other hand, is to produce a state of restlessness, both of mind and body. The nervous system is in an irritable condition, and requires something that will steady it down. A game may only add excitement to the restlessness. The brain is acting in an irregular, discursive manner, and needs some method of treatment which will reduce it to order. And this can best be obtained by means of a quiet hobby. The overworked man is like a horse that has been plodding along all day in the shafts with a heavy weight behind it; a little freedom, perhaps a gallop round a field, will do it more good than anything else. The over-worried man is like a horse that has been plunging aimlessly around, excited and irritable: an hour’s hard work between the shafts is what it needs. [Sidenote: Worries and hobbies.] Therefore, while the fatigued man requires recreation, the worried one will do better with some hobby that needs a certain amount of concentration. The form of hobby best suited to him depends on his tastes and capabilities. A celebrated physician once told me that when he found himself becoming worried he could quiet his mind most speedily by mathematical problems. They would do him far more good than any game or other form of recreation.
