It is a true saying that worry, not work, kills. People can get through an amazing amount of work if they do it in a quiet and methodical manner. One morning two men were walking along a road in the direction of a railway station. One of them was going at a steady pace, with a look of contentment about him, as if he were enjoying the walk. The other was hurrying along with quick, nervous steps, occasionally looking at his watch and breaking into a short run, while his strained expression and panting breath formed a marked contrast to the easy deportment of his friend. They both caught the train, but while one was cool and collected and felt invigorated for his work when he reached the terminus, the other was hot and flurried, and this gave him a bad start for the day. Moreover, each of them transacted his business in much the same way as he had walked to the station, one doing it quietly and methodically, while the other spent his time in rushing from one thing to another, taking his lunch in the fewest possible minutes, and constantly worrying himself and everyone else into the bargain. The singular part of it was that the quiet, steady-going man got through more work in the day than his friend did, and years later, when they had reached middle age, was as fit as ever for his business, whereas the other man was broken down by overwork, as he called it. In the last chapter we considered the question of physical and mental fatigue resulting from work. We purposely omitted the element of worry, which does more harm than all the other conditions of work put together. For worry does more than tire the mind--it demoralises it. In a certain war two companies of men had to march an equal distance in order to meet at a particular spot. The one arrived in perfect order, and with few signs of exhaustion, although the march had been an arduous one. The other company reached the place utterly done up and disorganised. It was all a question of leadership: the captain of the first company had known his way and kept his men in good order, while the captain of the second company had never been sure of himself, and had harassed his subordinates with a constant succession of orders and counter-orders, until they had hardly known whether they were on their heads or their heels. That was why they arrived looking completely demoralised. [Sidenote: Worry and the mind.]
