Human life has no meaning independent of itself. There is no cosmic force or deity to give it meaning or significance. There is no ultimate destiny for man. Such a belief is an illusion of humankind's infancy. The meaning of life is what we choose to give it. Meaning grows out of human purposes alone. Nature provides us with an infinite range of opportunities, but it is only our vision and our action that select and realize those that we desire.... Thus the good life is achieved, invented, fashioned in an active life of enterprise and endeavor. But whether or not an individual chooses to enter into the arena depends upon him alone. Those who do can find it energizing, exhilarating, full of triumph and satisfaction. In spite of failures, setbacks, suffering, and pain, life can be fun.
