“He who knows others is clever, but he who knows himself is enlightened. He who overcomes others is strong, but he who overcomes himself is mightier still. He is rich who knows when he has enough. He who acts with energy has strength of purpose. He who moves not from his proper place is long-lasting. He who dies, but perishes not, enjoys true longevity.”
― Lao Tzu, Tao Te Ching
