“Degrees of ability vary, but the basic principle remains the same: the degree of a man's independence, initiative and personal love for his work determines his talent as a worker and his worth as a man. Independence is the only gauge of human virtue and value. What a man is and makes of himself; not what he has or hasn't done for others. There is no substitute for personal dignity. There is no standard of personal dignity except independence.”

“If history teaches anything, it teaches that self-delusion in the face of unpleasant facts is folly.”

“Wait. You've got principles? We'll have to update your file.”
