Yeah. On a somewhat related note, my father always says that if you're "too smart" you'll never be rich, since you wouldn't take risks that you knew would have a very small likelihood of paying off.
My own personal theory is that most rich people are in league with Satan, but I don't say that out loud.
Of course, if you're "too smart" you might realise there's more to life than heap loads of cash, but that's another story...
