 I've been taught by Ben Graham to buy things on a quantitative basis, look around for things that are cheap, say a 1949 or 50, they made a big impression on me. So I went around looking for what I call you cigar butts of stocks. The cigar butt approach to buying stocks is that you walk down the street and you're looking around for cigar butts and you find this, honestly this terrible looking soggy ugly looking cigar. One puff left in it. But you pick it up and you get your one puff disgusted and you throw it away. But it's free. I mean it's cheap. You look around for another soggy, you know, one puffed cigar. Well that's what I did for years. It's a mistake. Although you make money doing it but you can't make it with big money. It's so much easier just to buy wonderful businesses. So now I would rather buy a wonderful business at a fair price than a fair business at a wonderful price. But in those days I was buying cheap stocks. You really want to be at a wonderful business because the time is the friend of the wonderful business. You keep compounding, it keeps doing more business and you keep making more money. Time is the enemy of the lousy business. But staying with those kind of businesses is a big mistake.
