I believe in the discipline of mastering the best that other people have ever figured out. I don't believe in just sitting down and trying to dream it all up yourself. Nobody's that smart.

The best thing a human being can do is to help another human being know more.

People have always had this craving to have someone tell them the future. Long ago, kings would hire people to read sheep guts. There's always been a market for people who pretend to know the future. Listening to today's forecasters is just as crazy as when the king hired the guy to look at the sheep guts.

I have a name for people who went to the extreme efficient market theory-which is "bonkers". It was an intellectually consistent theory that enabled them to do pretty mathematics. So I understand its seductiveness to people with large mathematical gifts. It just had a difficulty in that the fundamental assumption did not tie properly to reality.

To some extent, stocks are like Rembrandts. They sell based on what they've sold in the past. Bonds are much more rational. No-one thinks a bond's value will soar to the moon.

You can hire your advisor and then just apply a windage factor, like I used to do when I was a rifle shooter. I'd just adjust for so many miles an hour wind. Or you can learn the basic elements of your advisor's trade. You don't have to learn very much, by the way, because if you learn just a little then you can make him explain why he's right.

Creative accounting is an absolute curse to a civilization. One could argue that double-entry bookkeeping was one of history's great advances. Using accounting for fraud and folly is a disgrace. In a democracy, it often takes a scandal to trigger reform. Enron was the most obvious example of a business culture gone wrong in a long, long time.
