The important qualities you need are intelligence, patience, and interest, but the biggest thing is to be rational. In ‘97-8, people weren’t rational. People got caught up with what other people were doing. Don’t get caught up with what other people are doing. Being a contrarian isn’t the key, but being a crowd follower isn’t either. You need to detach yourself emotionally. You need to think about what is going on around you. Being in Omaha helps me in that regard. When I was in NYC, I had 50 people whispering in my ear before noon. It’s hard sometimes, like when the Internet craze hit. Nobody likes to see their neighbor doing stupid things and getting rich. It was like Cinderella’s ball, I think I’ll just have one more dance, it’s not midnight yet. Sounds simple – but it is hard to leave the party. The problem with stocks is they don’t have clocks. You don’t know when it will be midnight so you can leave the party. My partner Charlie Munger and Tony Nicely at Geico are always rational. 160 IQs can say stupid things that sound good. People do silly things, whether they have 120 IQ or 160. You can always improve your rational thought. Rationality is the only thing that helps you. One thing that could help would be to write down the reason you are buying a stock before your purchase. Write down “I am buying Microsoft @ $300B because…” Force yourself to write this down. It clarifies your mind and discipline. This exercise makes you more rational.
