No formula in finance tells you that the moat is 28 feet wide and 16 feet deep. That's what drives the academics crazy. They can compute standard deviations and betas, but they can't understand moats.

I think the oversight is great, and I think that oversight ought to be devoted almost entirely to the question is this being done at market you know. In other words, you want to make sure that the government isn't investing foolishly. But you don't want to care about which congressional districts it goes to or whether banks get favored over.

We believe that according the name 'investors' to institutions that trade actively is like calling someone who repeatedly engages in one-night stands a 'romantic.'

None of this means, however, that a business or stock is an intelligent purchase simply because it is unpopular; a contrarian approach is just as foolish as a follow-the-crowd strategy. What's required is thinking rather than polling. Unfortunately, Bertrand Russell's observation about life in general applies with unusual force in the financial world: "Most men would rather die than think. Many do."

Wide diversification is only required when investors do not understand what they are doing.

So smile when you read a headline that says "Investors lose as market falls." Edit it in your mind to "Disinvestors lose as market falls-but investors gain." Though writers often forget this truism, there is a buyer for every seller and what hurts one necessarily helps the other. (As they say in golf matches: "Every putt makes someone happy.")

The secret is to find what you love to do.I mean, I tell the students look for the job that you would take if you didn't need a job. I mean, it's that simple. And I was lucky enough to find it very early in life. And then the second thing is to have people around you that make feel good every day, and make you a better person than you otherwise would be.
