WATCH YOUR CHANCE and defend yourself against wrong, and do not be over- modest in your own cause; for there is a modesty that leads to sin, as well as a modesty that brings honor and favor.Do not be untrue to yourself in deference to another, or so diffident that you fail in your duty.Never remain silent when a word might put things right, for wisdom shows itself by speech, and a man’s education must find expression in words.Do not argue against the truth, but have a proper sense of your own ignorance.Never be ashamed to admit your mistakes, nor try to swim against the current.
