Strategic plans cause more dumb decisions than anything else in America.

My idea of a good place to shop is Costco - it has these heavily marbled fillet steaks. The idea of eating some wheat thing and washing it down with carrot juice has never appealed to me.

I regard the amount of brainpower going into money management as a national scandal. When some idiot would get rich, they'd say, 'Well, old Charlie was out in the field playing the big brass tuba on the day it rained gold.' A lot of people have become rich lately who were playing the tuba on the day it rained gold.

...in terms of business mistakes that I've seen over a long lifetime, I would say that trying to minimize taxes too much is one of the great standard causes of really dumb mistakes. I see terrible mistakes from people being overly motivated by tax considerations. Warren and I personally don't drill oil wells. We pay our taxes. And we've done pretty well, so far. Anytime somebody offers you a tax shelter from here on in life, my advice would be don't buy it.

I'm very pleased when the smartest people come [to the U.S.] and almost never pleased when the very bottom of the mental barrel comes in.

It's not the bad ideas that do you in, but the good ones.

Without numerical fluency, in the part of life most of us inhibit, you are like a one-legged man in an ass-kicking contest.
