Believe me, it takes a great man and one who has risen far above human weaknesses not to allow any of his time to be filched from him, and it follows that the life of such a man is very long because he has devoted wholly to himself whatever time he has had. None of it lay neglected and idle; none of it was under the control of another, for, guarding it most grudgingly, he found nothing that was worthy to be taken in exchange for his time.
