If you liked that, I would recommend Charlie Munger's book <a href="http://www.poorcharliesalmanack.com/" rel="nofollow">http://www.poorcharliesalmanack.com/</a> . It is a good read, and one that you can refer to over and over again. One of the sections in the book is also posted on Ycombinator at <a href="http://ycombinator.com/munger.html" rel="nofollow">http://ycombinator.com/munger.html</a> if you want to see the sort of thing he talks about in the book.
