Warren always said it’s probably always a mistake to marry for money and it’s really stupid if you’re already rich. - Charlie Munger

It is not usually the conscious malfeasance of your narrow professional adviser that does you in. Instead, your troubles come from his subconscious bias. His cognition will often be impaired, for your purposes, by financial incentives different from yours. And he will also suffer from the psychological defect caught by the proverb “To a man with a hammer, every problem looks like a nail.

So you can get very remarkable investment results if you think more like a winning pari mutuel player. Just think of it as a heavy-odds against game full of bullshit and craziness with an occasional mispriced something or other. And you’re probably not going to be smart enough to find thousands in a lifetime. And when you get a few, you really load up. It’s just that simple.

There’s another type of person I compare to an example from biology: When a bee finds nectar, it comes back and does a little dance that tells the rest of the hive, as a matter of genetic programming, which direction to go and how far. So about 40 or 50 years ago, some clever scientist stuck the nectar straight up. Well, the nectar’s never straight up in the ordinary life of a bee. The nectar’s out. So the bee finds the nectar and returns to the hive. But it doesn’t have the genetic programming to do a dance that says straight up. So what does it do? Well, if it were like Jack Welch, it would just sit there. But what it actually does is to dance this incoherent dance that gums things up. A lot of people are like that bee. They attempt to answer a question like that. And that is a huge mistake. Nobody expects you to know everything about everything. I try to get rid of people who always confidently answer questions about which they don’t have any real knowledge. To me, they’re like the bee dancing its incoherent dance. They’re just screwing up the hive.
