Investors... can't pick stocks that are better than average. Stocks are a good thing to own over time. There's only two things you can do wrong: You can buy the wrong ones, and you can buy or sell them at the wrong time. And the truth is you never need to sell them.

And they shouldn't argue about whether they put the resuscitation equipment a quarter of an inch this way or a quarter of an inch this way, or they shouldn't start criticizing the patient, because he didn't have a blood pressure test or something like that. They should do what's needed right now.
