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.

It is the direct man who strikes sledgehammer blows, who penetrates the very marrow of a subject at every stroke and gets the meat out of a proposition, who does things.

The strong man, the positive, decisive man who has a program and is determined to carry it out, cuts his way to his goal regardless of difficulties. It is the discouraged man who turns aside and takes a crooked path.

Real happiness is so simple that most people do not recognize it. They think it comes from doing something on a big scale, from a big fortune, or from some great achievement, when, in fact, it is derived from the simplest, the quietest, the most unpretentious things in the world.

A good laugh makes us better friends with ourselves and everybody around us.

The size and quality of your achievement will depend largely upon what sort of image you have of yourself at your best.
