My early work and publications centered around expanding on the analysis of life insurance in my dissertation and its relationship to investment banking.
I spent every night until four in the morning on my dissertation until I came to the point when I could not write another word not even the next letter. I went to bed. Eight o'clock the next morning I was up writing again.
I have come to believe that a great teacher is a great artist and that there are as few as there are any other great artists. Teaching might even be the greatest of the arts since the medium is the human mind and spirit.
