Move only when you have an advantage. It's very basic. You have to understand the odds and have the discipline to bet only when the odds are in your favor.
We've got great flexibility and a certain discipline in terms of not doing some foolish thing just to be active - discipline in avoiding just doing any damn thing just because you can't stand inactivity.
Berkshire was built on the eternal verities: basic mathematics, basic horse sense, basic fear, and basic diagnosis of human nature to make predictions regarding human behavior. We stuck to the basics with a certain amount of discipline and it has worked out quite well.
We get these questions a lot from the enterprising young. It's a very intelligent question: You look at some old guy who's rich and you ask, 'How can I become like you, except faster?' Spend each day trying to be a little wiser than you were when you woke up. Discharge your duties faithfully and well. Step by step you get ahead, but not necessarily in fast spurts. But you build discipline by preparing for fast spurts... Slug it out one inch at a time, day by day, at the end of the day -- if you live long enough -- most people get what they deserve.
For some odd reason, I had an early and extreme multidisciplinary cast of mind. I couldn't stand reaching for a small idea in my own discipline when there was a big idea right over the fence in somebody else's discipline. So I just grabbed in all directions for the big ideas that would really work.
Everybody engaged in complex work needs colleagues. Just the discipline of having to put your thoughts in order with somebody else is a very useful thing.”
You must know the big ideas in the big disciplines, and use them routinely - all of them, not just a few. Most people are trained in one model - economics, for example - and try to solve all problems in one way. You know the old saying: to the man with a hammer, the world looks like a nail. This is a dumb way of handling problems.
