The Art of Worldly Wisdom(126)

Folly consists not in committing Folly, but in not hiding it when committed. You should keep your desires sealed up, still more your defects. All go wrong sometimes, but the wise try to hide their errors while fools boast of them. Reputation depends more on what is hidden than on what is done; if a man does not live chastely, he must live cautiously. The errors of great men are like the eclipses of the greater lights. Even in friendship it is rare to expose one's failings to one's friend. Nay, one should conceal them from oneself if one can. But here one can help with that other great rule of life: learn to forget.
