Unless a man has pity, he is inhuman and not yet truly a man, for out of pity comes the balm which heals. Only good men weep. If a man has not yet wept at the world's pain, he is less than the dirt he walks upon, because dirt will nourish seed, root, stalk, leaf, and flower, but the spirit of a man without pity is barren and will bring forth nothing.
Try to learn to breathe deeply, really to taste food when you eat, and when you sleep really to sleep. Try as much as possible to be wholly alive with all your might, and when you laugh, laugh like hell. And when you get angry, get good and angry. Try to be alive. You will be dead soon enough.
