Man, proud man, Drest in a little brief authority, Most ignorant of what he's most assured.
William ShakespeareBeware Of entrance to a quarrel; but being in, Bear't that the opposed may beware of thee. Give every man thy ear, but few thy voice; Take each man's censure, but reserve thy judgment. Costly thy habit as thy purse can buy, But not express'd in fancy; rich, not gaudy; For the apparel oft proclaims the man.
William Shakespeare
