Charlie and I decided long ago that in an investment lifetime it's just too hard to make hundreds of smart decisions. That judgment became ever more compelling as Berkshire's capital mushroomed and the universe of investments that could significantly affect our results shrank dramatically. Therefore, we adopted a strategy that required our being smart - and not too smart at that - only a very few times. Indeed, we'll now settle for one good idea a year. (Charlie says it's my turn.)

Any lasting relationship needs non-negotiables. We made the decision early on never to be apart for longer than two weeks: 26 years married and we’ve only broken that rule once, by 11 hours, when my wife was in Sleepy Hollow. If I ever meet [director] Tim Burton, I’ll be having words.

The way I work is — I want to not have external stimulation. You can kind of see, on the walls are this light green. I'm told that at mental institutions they use that on the walls. It's like a calming color, it's not something that really stimulates you. What you can't see is the computer here, you only see the screen, but the main thing I worry about in my computer is — it doesn't have to be big and powerful, although I like that — it really has to be completely silent. I know people who work for Google and they have their own small data center at home, and I don't do that. My office is the most boring office you'll ever see. And I sit there alone in the quiet. If the cat comes up, it sits in my lap. And I want to hear the cat purring, not the sound of the fans in the computer.

Roll up your sleeves and work as a bouncer in a sex club or a warden in a lunatic asylum or a machine operator in a slaughterhouse. Drive a taxi for six months and you’ll have enough money to make a film. Walk on foot, learn languages and a craft or trade that has nothing to do with cinema. Filmmaking — like great literature — must have experience of life at its foundation. Read Conrad or Hemingway and you can tell how much real life is in those books.

I believe the common denominator of the universe is not harmony; but chaos, hostility and murder.

No. Go for it, as I did it. Go for all the mistakes. I made so many mistakes in doing my films. They all have a stutter or a limp or they are squint-eyed. Hardly anyone notices it, but I notice. Make your mistakes. Get arrested if you trespass. Yes. Do it. There’s nothing wrong with spending a night or two in jail. I’ve done that. Don’t be afraid of the grizzly bear behind you. Travel on foot. Read books.
