I get flack for saying [when I visit a college and give a speech], "This is a nice college, but the really great educator is McDonald's." They hate me for saying this and think I'm a slimy creature. But McDonald's hires people with bad work habits, trains them, and teaches them to come to work on time and have good work habits. I think a lot of what goes on there is better than at Harvard.
Charlie MungerSince those donโt hit financial reports, the opportunities you had but didnโt accept, most people donโt bother thinking about them very much. At least that is a mistake we donโt make. We rub our own noses in our mistakes in blowing opportunities, as we just did.
Charlie MungerPart of [having uncommon sense] is being able to tune out folly, as opposed to recognizing wisdom. If you bat away many things, you don't clutter yourself.
Charlie MungerBerkshire's whole record has been achieved without paying one ounce of attention to the efficient market theory in its hard form. And not one ounce of attention to the descendants of that idea, which came out of academic economics and went into corporate finance and morphed into such obscenities as the capital asset pricing model, which we also paid no attention to. I think you'd have to believe in the tooth fairy to believe that you could easily outperform the market by seven-percentage points per annum just by investing in high volatility stocks.
