“Achievement of your happiness is the only moral purpose of your life, and that happiness, not pain or mindless self-indulgence, is the proof of your moral integrity, since it is the proof and the result of your loyalty to the achievement of your values.”

Ayn Rand was a Russian-American novelist and philosopher of the 20th century. She is best known for her novels *The Fountainhead* and *Atlas Shrugged*, which explore themes of individualism, capitalism, and rational egoism. Her ideas significantly influenced libertarian and objectivist thought.
