Listen much, keep silent when in doubt, and always take heed of the tongue; thou wilt make few mistakes. See much, beware of pitfalls, and always give heed to thy walk; thou wilt have little to rue. If thy words are seldom wrong, thy deeds leave little to rue, pay will follow.
When a man's knowledge is sufficient to attain, and his virtue is not sufficient to enable him to hold, whatever he may have gained, he will lose again.
