Questioner: When you try to arrive at the valuation number using the discount rate…

Munger: Your opportunity cost is so great. Considering everything else, you should forget about it. Most people don’t pay enough attention to opportunity cost. Bridge players know about opportunity cost. Poker players know about opportunity cost. American faculty members and other important people, they hardly know their ass from a plate of hot squash.

We don’t use numeric formulas that way. We take into account a whole lot of factors. It’s a multifactor thing. There are tradeoffs between factors. It’s just like a bridge hand. You have to think of a lot of different things at once.

There’s never going to be a formula that will make you rich just by going through some little process. If that were true, every mathematical nerd that gets A’s in algebra would be rich.
