“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.”

“Be proactive. Begin with the end in mind.”

“You do not rise to the level of your goals. You fall to the level of your systems.”

“I learned that courage was not the absence of fear, but the triumph over it. The brave man is not he who does not feel afraid, but he who conquers that fear.”

“If you don't like something, change it. If you can't change it, change your attitude.”
