I started Wharton 55 years ago last month. And the first thing I remember learning there is that you can’t tell the quality of a decision from the outcome. And that pervades my thinking. And I think it’s very important. And then I played backgammon with my good friend Bruce Newburg, out in Los Angeles, and you need some crazy number to win, and you get it. That doesn’t mean you’re a good player. It means you were lucky.
I think I’ve been the luckiest person on the planet. And I think it was to that that people were responding. But I get into arguments with people and a lot of people say, “Oh—!” Well, what started the article is, I read a piece that quoted some Silicon Valley guy who says, “Success is never accidental. You make your own luck.” And I don’t agree. I think luck is a real thing and it’s important and it’s inherently unfair, but that’s life.
For most investors, loss is the bad outcome they’re concerned with. But, the truth is, if it’s the probability of bad outcomes, there are really at least two risks that we should think about. One is the probability of loss and the other is the probability of gains that you miss out on.
