The best of us get on one another's nerves, even under ordinary conditions, and it takes infinite pains and self-control to get through a trying day in a busy office without striking sparks somewhere. If there is a secret of success, and some of the advertisements seem trying to persuade us that it is all secret, it is the ability to work efficiently and pleasantly with other people. The business man never works alone. He is caught in the clutches of civilization and there is no escape. He is like a man climbing a mountain tied to a lot of other men climbing the same mountain. What each one does affects all the others.
