Obviously if you want to get good at something which is competitive, you have to think about it and practice a lot. You have to keep learning because world keeps changing and competitors keep learning. You have to go to bed wiser than you got up. As you try to master what you are trying to do โ people who do that almost never fail utterly. Very few have ever failed with that approach. You may rise slowly, but you are sure to rise.
Charlie MungerIf the same family were always on the bottom, then you'd have big resentments. But if DuPonts go down and Pampered Chef up, [that's good]. That much churn makes people think the system is fairer. Buffett: We don't like churn now, but we liked it more 30-40 years ago.
Charlie MungerThe world of derivatives is full of holes that very few people are really aware of. It's like hydrogen and oxygen sitting on the corner waiting for a little flame.
Charlie MungerIt's my guess that something like 5% of GDP goes to money management and itsattendant friction. I define it broadly - annuities, incentive pay, all trading, etc. Nobody else has used figures that high, but that's my guess. Worst of all, the people doing this are among the best and the brightest. Hundreds and thousands of engineers, etc. are going into hedge funds and investment banking. That is not an intelligent allocation of the brainpower of the civilization.
