It's hard to predict what will happen with two brands in a market. Sometimes they will behave in a gentlemanly way, and sometimes they'll pound each other. I know of no way to predict whether they'll compete moderately or to the death. If you could figure it out, you could make a lot of money.

It's dishonourable to stay stupider than you need to be

You must force yourself to consider opposing arguments. Especially when they challenge your best loved ideas.

There are a lot of things in life way more important than money. All that said, some people do get confused. I play golf with a man who says, " What good is health? You can't buy money with it."

There's a lot wrong [with American universities]. I'd remove 3/4 of the faculty - everything but the hard sciences. But nobody's going to do that, so we'll have to live with the defects. It's amazing how wrongheaded [the teaching is]. There is fatal disconnectedness. You have these squirrelly people in each department who don't see the big picture.

For years I have read the morning paper and harrumphed. There's a lot to harrumph about now.

Any year that you don't destroy one of your best-loved ideas is probably a wasted year
