 Because if they get lucky, let's just say if they get lucky, if they buy an Apple or a Microsoft and it does well, well, then they think they're the next Warren Buffett. And the rest of their career will be spent making trades that might not be such great trades, but just because they have this false sense of security that they're a great stock picker. It doesn't mean that that's necessarily the case. They could have gotten lucky. So don't confuse luck with skill.
