We try to exert a Ted Williams kind of discipline. In his book The Science of Hitting, Ted explains that he carved the strike zone into 77 cells, each the size of a baseball. Swinging only at balls in his "best" cell, he knew, would allow him to bat .400; reaching for balls in his "worst" spot, the low outside corner of the strike zone, would reduce him to .230. In other words, waiting for the fat pitch would mean a trip to the Hall of Fame; swinging indiscriminately would mean a ticket to the minors.

Charlie and I have made a dozen or so very big decisions relative to net worth, although not as big as they should have been. And in each of those, we've known that we were almost certain to be right going in.

We do not have, nor have had, and never will have an opinion about where the stock market, interest rates, or business activity will be a year from now.

A hyperactive stock market is the pickpocket of enterprise.

I'm sitting with six and a half billion dollars we're going to use to close the Mars-Wrigley deal on October 6. I've got to hand over that six and a half billion on October 6. Now, I have to be very careful about who I leave it in between now and then, because they're expecting that he show up.

In an inflationary world, a toll bridge (like company) would be a great thing to own because you've laid out the capital costs. You built it in old dollars and you don't have to keep replacing it.

Cash, though, is to a business as oxygen is to an individual: never thought about when it is present, the only thing in mind when it is absent... When bills come due, only cash is legal tender. Don't leave home without it.
