Work kills no one, but worry has killed multitudes… Worry not only saps vitality and wastes energy, but it also seriously affects the quality of one's work. It cuts down ability. A man cannot get the highest quality of efficiency into his work when his mind is troubled. The mental faculties must have perfect freedom before they will give out their best. A troubled brain cannot think clearly, vigorously, and logically.
