" My mind went back to my school-days and an old gentleman talking to the class about careers. He had said: “If you decide to become a veterinary surgeon you will never grow rich but you will have a life of endless interest and variety.” I laughed aloud in the darkness and as I got into the car I was still chuckling. That old chap certainly wasn’t kidding. Variety. That was it—variety. "
