Good talk rises upon much self-discipline.
Exhaust neither the topic nor the audience. O Lord, please fill my mouth with worthwhile stuff, and nudge me when I've said enough. A wise man will not communicate his differing thoughts to unprepared minds, or in a disorderly manner. Be sure, when you think you are being extremely tactful, that you are not in reality running away from something you ought to face. It is perhaps the only weapon with which it is possible to stab oneself in one's own back.
