John D. Rockefeller spent much of his life doing something that made him one of the wealthiest people in modern history: making money. Yet Rockefeller, the industrialist who built the Standard Oil empire, believed wealth could become meaningless when accumulation itself became the purpose of existence. His sharpest warning was aimed not at poverty, ambition or financial success, but at the person who allowed money to consume every waking hour.
That contradiction gives his famous words their enduring force. Rockefeller knew extraordinary wealth firsthand, but he argued that money should remain a means rather than become the meaning of life.
