You need a lot of curiosity for a long, long time.

A pin lies in wait for every bubble. And when the two eventually meet, a new wave of investors learns some very old lessons: First, many in Wall Street (a community in which quality control is not prized) will sell investors anything they will buy. Second, speculation is most dangerous when it looks easiest.

That would be nice if [people] stuck [treasury bills] all under a mattress, but they got to buy something with them. Sometimes they buy a treasury note, sometimes they set up sovereign wealth funds. They can do all kinds of things. They can buy our companies here. As long as we consume more than we produce, and we trade away little pieces of the country daily, they're going to own something. Now, they can't run from American assets. I mean every day the rest of the world is going to have about two billion more of American assets than we have, as long as they sell us these goods.

People who watch their weight, golf scores, and fuel bills seem to shun quantitative evaluation of their investment management skills although it involves the most important client in the world-themselves.

Time is the friend of the wonderful business. It's the enemy of the lousy business. If you're in a lousy business for a long time, you're going to get a lousy result, even if you buy it cheap. If you're in a wonderful business for a long time, even if you pay a little too much going in, you're going to get a wonderful result if you stay in a long time.

An argument is made that there are just too many question marks about the near future; wouldn't it be better to wait until things clear up a bit? You know the prose: "Maintain buying reserves until current uncertainties are resolved," etc. Before reaching for that crutch, face up to two unpleasant facts: The future is never clear and you pay a very high price for a cheery consensus. Uncertainty actually is the friend of the buyer of long-term values.

We're perfectly willing to trade away a big payoff for a certain payoff.
