Sixth, it’s important to have both sides of your brain working, not just the left side (the side that.s good at math and organization.) In business school, I met a lot of people who were incredibly smart. But those who were majoring in finance couldn’t write worth a damn and had a hard time coming up with inventive ways to look at a problem. I was a little shocked at this. I later learned that some really smart people have only one side of their brains working, and that is enough to do very well in the world but not enough to be an entrepreneurial investor who thinks differently from the masses. On the other hand, if the right side of your brain is dominant, you probably loath math and therefore you don’t often find these people in the world of finance to begin with. So finance people tend to be very left-brain oriented and I think that’s a problem. I believe a great investor needs to have both sides turned on. As an investor, you need to perform calculations and have a logical investment thesis. This is your left brain working. But you also need to be able to do things such as judging a management team from subtle cues they give off. You need to be able to step back and take a big picture view of certain situations rather than analyzing them to death. You need to have a sense of humor and humility and common sense. And most important, I believe you need to be a good writer. Look at Buffett; he’s one of the best writers ever in the business world. It’s not a coincidence that he’s also one of the best investors of all time. If you can’t write clearly, it is my opinion that you don’t think very clearly. And if you don’t think clearly, you’re in trouble. There are a lot of people who have genius IQs who can’t think clearly, though they can figure out bond or option pricing in their heads.
The whole speech is worth reading. It hit a chord with me because the ultimate reason why I write this blog is to become a better investor. Writing helps me to clarify my thinking about thorny topics such as inflation, investing, asset allocation and tax planning. I know I would be thinking a lot less clearly about these things if I didn’t write about them from time to time.
