Somebody talked me into writing an autobiography about six or seven years ago. And I said I'd try. We talked into a tape recorder, and after a couple of months, I said, To hell with it. I was so depressed. It was like saying, 'This is the end.' I was more interested in what the hell was coming the next day or the next week.
