Oil is better than sand for keeping this vast machinery in good running condition. Do not shovel grit or gravel stones upon the bearings. A tiny copper shaving in a wheel box, or a scratch on a journal, may set a railway train on fire. The running of the business world is damaged by whatever creates friction. Anxiety mars one's work. Nobody can do his best when, fevered by worry. One may rush, and always be in great haste, and may talk about being busy, fuming and sweating as if he were doing ten men's duties; and yet some quiet person alongside, who is moving leisurely and without anxious haste, is probably accomplishing twice as much, and doing it better. Fluster unfits one for good work. Have you not sometimes seen a business manager whose stiffness would serve as "a good example to a poker?" He acts toward his employees as the father of Frederick the Great did toward his subjects, caning them on the streets, and shouting, "I wish to be loved and not feared." "Growl, Spitfire and Brothers," says Talmage, "wonder why they fail, while Messrs. Merriman and Warmheart succeed." There is no investment a business man can make that will pay him a greater per cent, than patience and amiability. Good humor will sell the most goods. John Wanamaker's clerks have been heard to say: "We can work better for a week after a pleasant 'Good morning' from Mr. Wanamaker." This kindly disposition and cheerful manner, and a desire to create a pleasant feeling and diffuse good cheer among those who work for him, have had a great deal to do with the great merchant's remarkable success. On the other hand, a man who easily finds fault, and is never generous-spirited, who never commends the work of subordinates when he can do so justly, who is unwilling to brighten their hours, fails to secure the best of service. "Why not try love's way?" It will pay better, and be better. A habit of cheerfulness, enabling one to transmute apparent misfortunes into real blessings, is a fortune to a young man or young woman just crossing the threshold of active life. There is nothing but ill fortune in a habit of grumbling, which "requires no talent, no self-denial, no brains, no character." Grumbling only makes an employee more uncomfortable, and may cause his dismissal. No one would or should wish to make him do grudgingly what so many others would be glad to do in a cheerful spirit. If you dislike your position, complain to no one, least of all to your employer. Fill the place as it was never filled before. Crowd it to overflowing. Make yourself more competent for it. Show that you are abundantly worthy of better things. Express yourself in this manner as freely as you please, for it is the only way that will count.
