The way I feel at the moment, why stop? I do it because I enjoy it. And yesterday is gone. I don't care what happened yesterday. What else would I do? People retire to die. I don't get any individual pleasure because we don't win races or titles in this job. I'm like most business people. You look back at the end of the year and you see what you've achieved by working out how much money the company has made. That's it.
