"My mother drew a distinction between achievement and success. She said that achievement is the knowledge that you have studied and worked hard and done the best that is in you. Success is being praised by others. That is nice but not as important or satisfying. Always aim for achievement and forget about success."
"Somehow I can't believe that there are any heights that can't be scaled by a man who knows the secrets of making dreams come true. This special secret, it seems to me, can be summarized in four C s. They are curiosity, confidence, courage, and constancy, and the greatest of all is confidence. When you believe in a thing, believe in it all the way, implicitly and unquestionable."
"Nothing is as difficult as to achieve results in this world if one is filled full of great tolerance and the milk of human kindness. The person who achieves must generally be a one-idea individual, concentrated entirely on that one idea, and ruthless in his aspect toward other men and other ideas."
"The truth of the matter is that there's nothing you can't accomplish if: (1) You clearly decide what it is that you're absolutely committed to achieving, (2) You're willing to take massive action, (3) You notice what's working or not, and (4) You continue to change your approach until you achieve what you want, using whatever life gives you along the way."
