说话要谨慎。与对手交谈时，要审慎；与其他人交谈，也要小心，是为了言语得体。补充一句话总是有机会，收回一句话却永远不可能。说话要像立遗嘱：言词越少，纷争就越少。在细微小事上锻炼自己的言谈，从而应对更重要的讲话。深藏不露的秘密有点神圣的光彩。口风不紧之人，很容易跌倒或失败。
be careful in speaking. with your rivals from prudence; with others for the sake of appearance. there is always time to add a word, never to withdraw one. talk as if you were making your will: the fewer words the less litigation. in trivial matters exercise yourself for the more weighty matters of speech. profound secrecy has some of the lustre of the divine. he who speaks lightly soon falls or fails.
