Knowledge is not wisdom; cleverness is not without awareness of our death, not without recalling just how brief our flare is. He who overreaches, will in his overreaching, lose what he possesses, betray what he has now. Question everything. learn something. Answer nothing.The wisest men follow their own direction. Talk sense to a fool and he will call you foolish. In case of dissension, never dare to judge till you've heard the other side.
