When clouds rise in the sky, it is a sign that it will rain. There is nothing to do but to wait until the rain falls. It is the same in life when destiny is at work. We should not worry and seek to shape the future by interfering in things before the time is ripe. We should quietly fortify the body with food and drink and the mind with gladness and good cheer. Fate comes when it will, and thus we are ready.
—I Ching, Hexagram 5
