Self-esteem

"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 â€" Purpose, as his choice of happiness, which that too, must process to achieve -- Self-esteem, as his inviolate certainty that his mind is competent to think and his person is worthy of happiness, which means: worthy of living." [Ayn Rand, For the New Intellectual, p128]
