So some guy may know how to make money in cocoa beans, but I don't so I just let him have that. But it's got to be something I understand. It's got to be a business with fundamentally good economics. It's got to be a management that I like and trust and admire. And it's got to be a price that makes sense.

When forced to choose, I will not trade even a night's sleep for the chance of extra profits.

I asked him what he wanted to do for his career, and he replied that he wanted to go into a particular field, but thought he should work for McKinsey for a few years first to add to his resume. To me that's like saving sex for your old age. It makes no sense.

The big question about how people behave is whether they've got an Inner Scorecard or an Outer Scorecard. It helps if you can be satisfied with an Inner Scorecard.

As I have mentioned before, we cannot make the same sort of money out of permanent ownership of controlled businesses that can be made from buying and reselling such businesses, or from skilled investment in marketable securities. Nevertheless, they offer a pleasant long term form of activity (when conducted in conjunction with high grade, able people) at satisfactory rates of return.

Wall Street makes its money on activity. You make your money on inactivity.

I'm putting all my money in the Chinese toy market.
