I always enjoy taking a few minutes to flip through Poor Charlie’s Almanack. I found the following passage particularly interesting and wanted to share it (Emphasis mine). Munger discusses the importance of “The Circle of Competence,” which helps explain what has fueled Berkshire’s unrivaled performance over the last several decades.
The cash register was one of the great contributions to civilization. It’s a wonderful story. Patterson was a small retail merchant who didn’t make any money. One day, somebody sold him a crude cash register which he put into his retail operation. And it instantly changed from losing money to earning a profit because it made it so much harder for the employees to steal.
But Patterson, having the kind of mind that he did, didn’t think, “Oh, good for my retail business.” He thought, “I’m going into the cash register business.” And, of course, he created National Cash Register.
And he “surfed”. He got the best distribution system, the biggest collection of patents and the best of everything. He was a fanatic about everything important as the technology developed. I have in my files an early National Cash Register Company report in which Patterson described his methods and objectives. And a well-educated orangutan could see that buying into partnership with Patterson in those early days, given his notions about the cash register business, was a total 100% cinch.
And, of course, that’s exactly what an investor should be looking for. In a long life, you can expect to profit heavily from at least a few of those opportunities if you develop the wisdom and will to seize them. At any rate, “surfing” is a very powerful model.
However, Berkshire Hathaway, by and large, does not invest in these people that are “surfing” on complicated technology. After all, we’re cranky and idiosyncratic—as you may have noticed.
And Warren and I don’t feel like we have any great advantage in the high-tech sector. In fact, we feel like we’re at a big disadvantage in trying to understand the nature of technical developments in software, computer chips or what have you. So we tend to avoid that stuff, based on our personal inadequacies.
Again, that is a very, very powerful idea. Every person is going to have a circle of competence. And it’s going to be very hard to advance that circle. If I had to make my living as a musician…. I can’t even think of a level low enough to describe where I would be sorted out to if music were the measuring standard of the civilization.
So you have to figure out what your own aptitudes are. If you play games where other people have the aptitudes and you don’t, you’re going to lose. And that’s as close to certain as any prediction that you can make. You have to figure out where you’ve got an edge. And you’ve got to play within your own circle of competence.
If you want to be the best tennis player in the world, you may start out trying and soon find out that it’s hopeless—that other people blow right by you. However, if you want to become the best plumbing contractor in Bemidji, that is probably doable by two-thirds of you. It takes a will. It takes the intelligence. But after a while, you’d gradually know all about the plumbing business in Bemidji and master the art. That is an attainable objective, given enough discipline. And people who could never win a chess tournament or stand in center court in a respectable tennis tournament can rise quite high in life by slowly developing a circle of competence- which results partly from what they were born with and partly from what they slowly develop through work.
So some edges can be acquired. And the game of life to some extent for most of us trying is to be something like a good plumbing contractor in Bemidji. Very few of us are chosen to win the world’s chess tournaments.
