I would say that life at 84, I am having as much fun as I've ever had in my life. I mean I get to do what I love every day with the people I love-and it just doesn't get any better than that.

We are trading away a little bit of our country all the time for this access consumption that we have over what we've produced. That is not good. I think it's terrible over time. But our country's productive grows enough so we actually can do that, and we'll still be better off. We just don't be as well off as if we hadn't done it.

I have three boxes on my desk: In, Out, and Too Hard.

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

I bought a company in the mid-90s called Dexter Shoe and paid $400 million for it. And it went to zero. And I gave about $400 million worth of Berkshire stock, which is probably now worth $400 billion. But I've made lots of dumb decisions. That's part of the game.

I never buy anything unless I can fill out on a piece of paper my reasons. I may be wrong, but I would know the answer to that ...I'm paying $32 billion today for the Coca Cola Company because... If you can't answer that question, you shouldn't buy it. If you can answer that question, and you do it a few times, you'll make a lot of money.

If you are a professional and have confidence, then I would advocate lots of concentration.
