That's the first thing I thought, too.

I would advise OP to read his biography, and there are at least two books that I know of, The Snowball and Buffett.  I've read both, and they're pretty good.

The main thing with Buffett is that he is absolutely obsessed with making money and reading annual reports.  He is single-minded in his drive to find undervalued stocks and he does it very well.  Basically, he's a value investor who uses fundamental analysis to buy cheap stocks (or private businesses).  What sets him apart from everyone else is that he does his homework, doesn't often sell stocks, and doesn't let emotion guide his trading.  There's a lot of stuff I could write, but the authors of his biographies lay it all out pretty well.
