"When people get angry they lose all sense of happiness. Even if they are good-looking and normally peaceful, their faces turn livid and ugly. Anger upsets their physical well-being and disturbs their rest; it destroys their appetites and makes them age prematurely. Happiness, peace, and sleep evade them, and they no longer appreciate people who have helped them and deserve their trust and gratitude."
H.H. Dalai Lama
