懂得保留绝招的艺术。大师在授徒之时，便是凭这个箴言保持尊贵的地位：永远领先于人，才能保持大师的地位。教授别人，一定要讲究技巧。知识和礼物的来源都不能告诉他人，这样，才能保持他人对你的敬仰和遵从。不管是娱乐还是教学，都要遵循这个规则：保持人们对你的期待，保持自己的优势。懂得保留，对人生、对成功，都是重要的法则，对那些身居高位的人来说，尤其如此。
keep to yourself the final touches of your art. this is a maxim of the great masters who pride themselves on this subtlety in teaching their pupils: one must always remain superior, remain master. one must teach an art artfully. the source of knowledge need not be pointed out no more than that of giving. by this means a man preserves the respect and the dependence of others. in amusing and teaching you must keep to the rule: keep up expectation and advance in perfection. to keep a reserve is a great rule for life and for success, especially for those in high place.
