"To say "I have to" is to speak the language of compulsion, duty, authority -- the language of injunctions imposed on us from without. Objectivism is not a duty ethic, but an ethic of values, the ultimate value being one's own life and happiness. The language of values is "I want" and "I will": I want this, and I will do what it takes to get it."
