" Quit while you’re ahead. All the best gamblers do. A fine retreat matters as much as a stylish attack. As soon as they are enough—even when they are many—cash in your deeds. A long run of good fortune is always suspicious. You’re safer when good luck alternates with bad, and, besides, that makes for bittersweet enjoyment. When luck comes racing in on us, it is more likely to slip and smash everything to pieces. Sometimes Lady Luck compensates us, trading intensity for duration. She grows tired when she has to carry someone on her back for a long time. "
