"The most extreme mistakes in Berkshire’s history have been mistakes of omission. We saw it, but didn’t act on it. They’re huge mistakes — we’ve lost billions. And we keep doing it. We’re getting better at it. We never get over it. There are two types of mistakes: 1) doing nothing; what Warren calls "sucking my thumb" and 2) buying with an eyedropper things we should be buying a lot of." -Charlie Munger
