Here Lear’s fool gives advice that could by usefully followed by most of us. I also like his willingness to take back his advice if you happen to find a better source of wisdom. Which of course you know you won’t, at least if you’ve read your Erasmus.
Let go thy hold when a great wheel runs down a hill, lest it break thy neck with following it; but the great one that goes upward, let him draw thee after. When a wise man gives thee better counsel, give me mine again. I would have none but knaves follow it, since a fool gives it.
