If you can get good at destroying your own wrong ideas, that is a great gift.
My idea of a good place to shop is Costco - it has these heavily marbled fillet steaks. The idea of eating some wheat thing and washing it down with carrot juice has never appealed to me.
We believe that almost all really good investment records will involve relatively little diversification. The basic idea that it was hard to find good investments and that you wanted to be in good investments, and therefore, you'd just find a few of them that you knew a lot about and concentrate on those seemed to me such an obviously good idea. And indeed, it's proven to be an obviously good idea. Yet 98% of the investing world doesn't follow it. That's been good for us.
If you get into the mental habit of relating what you're reading to the basic structure of the underlying ideas being demonstrated, you gradually accumulate some wisdom.
There are exceptional loyalties and there are old fashion ideas about how you get loyalties, and after all the auditorium is full of people who have co-owned shares with the managers for many decades, and in many cases they co-invested when everyone was young and obscure. Also when you come back to a place like that you are celebrating old loyalties, and of course the basic idea behind so much of Berkshire is the old fashioned idea that the best way to get loyalty is to deserve loyalty.
I always like it when someone attractive to me agrees with me, so I have fond memories of Phil Fisher. The idea that it was hard to find good investments, so concentrate in a few, seems to me to be an obviously good idea. But 98% of the investment world doesn't think this way.
You must know the big ideas in the big disciplines, and use them routinely - all of them, not just a few. Most people are trained in one model - economics, for example - and try to solve all problems in one way. You know the old saying: to the man with a hammer, the world looks like a nail. This is a dumb way of handling problems.
I think the idea that the hedge fund manager gets lower taxes than the taxi driver or the physics professor is insane. The legislators who leave that policy in place are derelict in their duties to be rational and fair. There are plenty of them in both political parties. It's totally outrageous.
It's very useful to have a good grasp of all the big ideas in hard and soft science. A, it gives perspective. B, it gives a way for you to organize and file away experience in your head, so to speak.
The idea of excessive diversification is madness. Wide diversification, which necessarily includes investment in mediocre businesses, only guarantees ordinary results.
The idea of excessive diversification is madness.
Rationality is not just something you do so that you can make more money, it is a binding principle. Rationality is a really good idea. You must avoid the nonsense that is conventional in one's own time. It requires developing systems of thought that improve your batting average over time.
You have to have a temperament to grab ideas and do sensible things. Most people don’t grab the right ideas or don’t know what to do with them.
An idea or a fact is not worth more merely because it's more available to you.
