"In these strenuous times, we are likely to become morbid and look constantly on the dark side of life, and spend entirely too much time considering and brooding over what we can't do, rather than what we can do, and instead of growing morose and despondent over opportunities either real or imaginary that are shut from us, let us rejoice at the many unexplored fields in which there is unlimited fame and fortune to the successful explorer and upon which there is no color line; simply the survival of the fittest."
