The trivial irritations that produce eruptions of rage are by no means trivial. Rage is like a cellular anger. It leaps up in defense of character, rejects interference, insists on maintaining our habitual way of life. "Don't tell me what to do!" "Let me do it my way!" "This is how I like it!" Irritability: a display of the raw urge to live. It shows the attachment of the flesh to living.
— James Hillman, The Force of Character
