"He who uses trickery should at least make use of his judgment to learn that he can scarcely hide treacherous conduct for very long among clever men who are determined to find him out, although they may pretend to be deceived in order to disguise their knowledge of his deceitfulness."

Never have anything to do with an unlucky place, or an unlucky man. I have seen many clever men, very clever men, who had not shoes to their feet. I never act with them. Their advice sounds very well, but they cannot get on themselves; and if they cannot do good to themselves, how can they do good to me?
