“We only regard errors as being things that are within our circle of competence. So if somebody knows how to make money in cocoa beans, or they know how to make money in a software company or anything, and we miss that, that is not an error, as far as we’re concerned. What’s an error is when it’s something we understand, and we stand there and stare at it, and we don’t do anything. Or worse yet, what really gets me is when we do something very small with it. We do an eyedropper’s worth of it, when we could do it very big.”
—Warren Buffett.
