I see almost no change in the price of the composite product that flows through Costco I don't feel sorry for the people who pay $27 million for an 8,000-square-foot condo in Manhattan. So inflation comes in places.

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.
