Imitation is the sincerest form of flattery.

When you have nothing to say, say nothing; a weak defense strengthens your opponent, and silence is less injurious than a bad reply.

It is always safe to learn, even from our enemies, seldom safe to venture to instruct, even our friends.

None are so fond of secrets as those who do not mean to keep them; such persons covet secrets as a spendthrift covets money, for the purpose of circulation.
