 I fooled around doing a lot of things between about age 11 and 19 in the stock market. I did charts, I did all kinds of technical analysis, I read every book I could get on the subject, and I didn't do that well, I didn't do terrible, but I was really just floundering around. But that meant by the age of 19, when I read Ben Graham's book, I was at the University of Nebraska in Lincoln, I went and bought this book called The Intelligent Investor, just come out, and it had an enormous impact on me. Now if I hadn't done, in the previous eight years, if I hadn't been all over the lot, I'm not so sure that that book would have had the same impact on me. I mean, I was, by that time I was prepared to read Ben Graham's book, which changed my life financially in an incredible way. I mean, I wouldn't be up here today if I hadn't read that book. I would say that first eight years of fooling around, even though it produced nothing financially to speak of, produced a lot in terms of getting my mind prepared for when I really did read something that made sense.
