Leave your luck while still winning. All the bvest players do it. A fine retreat is as good as a gallant attack. Bring your exploits under cover when there are enough, or even when there are many of them. Luck too long lasting is always suspicious; alternating luck seems safer, and is even sweeter to the taste for a little infusion of bittersweet. The higher the heap of luck, the greater the risk of a slip, and down comes all. Fortune pays you sometimes for the intensity of her favors by the shortness of their duration. She soon tires of carrying anyone long on her shoulders.
