Many people complain that they have broken down through over-work. In the majority of such cases, the break-down is more frequently the result of foolishly wasted energy. If you would secure health, you must learn to work without friction. To become anxious or excited or to worry over needless details is to invite a breakdown. Work whether of brain or body is beneficial and health-giving and the man who can work with a steady and calm persistency, free from all anxiety and worry, and with his mind utterly oblivious to all but the work he has in hand, will not only accomplish far more than the man who is always hurried and anxious, but he will retain his health, a boon which the other quickly forfeits.
