"Dagny, there's nothing of any importance in life — except how well you do your work. Nothing. Only that. Whatever else you are, will come from that. It's the only measure of human value. All the codes of ethics they'll try to ram down your throat are just so much paper money put out by swindlers to fleece people of their virtues. The code of competence is the only system of morality that's on a gold standard. When you grow up, you'll know what I mean."
