A Quote by Ayn Rand on achievement, certainty, choice, competence, existence, happiness, honesty, independence, integrity, justice, knowledge, life, mind, morality, pride, purpose, reason, rest, self-esteem, and worth

My morality, the morality of reason, is contained in a single axiom: existence exists - and in a single choice: to live. The rest proceeds from these. To live, man must hold three things as the supreme and ruling values of his life: Reason - Purpose - Self-esteem. Reason, as his only tool of knowledge - Purpose, as his choice of the happiness which that tool must proceed to achieve - Self-esteem, as his inviolate certainty that his mind is competent to think and his person is worth of happiness, which means: is worthy of living. These three values imply and require all of man's virtues, and all his virtues pertain to the relation of existence and consciousness: rationality, independence, integrity, honesty, justice, productiveness, pride.
