Being rational is a moral Imperative. You should never be stupider than you need to be.
Charlie MungerI'm used to people with very high IQs knowing how to recognize reality, but there's a huge human tendency where it may be instructive to think that whatever you're doing to succeed is all right.
Charlie MungerEvery business tries to turn this year's success into next year's greater success. It's hard for me to see why Microsoft is sinful to do this. If it's a sin, then I hope all of Berkshire Hathaway's subsidiaries are sinners. Someone whose salary is paid by U.S.taxpayers is happy to dramatically weaken the one place where we're winning big?!
Charlie MungerOur standard prescription for the know-nothing investor with a long-term time horizon is a no-load index fund. I think that works better than relying on your stock broker. The people who are telling you to do something else are all being paid by commissions or fees. The result is that while index fund investing is becoming more and more popular, by and large it's not the individual investors that are doing it. It's the institutions.
