There are many people who have no desire to do anything differently than anyone else. And that's fine. We need to have people who are technically expert: people who play wonderful third fiddle, if you will, or people who carry out what we call normal experiments in science (ones which sort of fill in the tiny little holes which were left by the great creators). But some people want to push beyond that. And that's a personality kind of thing. It's nothing to do with how smart they are. It's whether they're the kinds of people who like to confront obstacles. Only people who've got that kind of irritation...irritability...where they're not satisfied just to do what other people want to do, but who really want to put themselves on the line and take a risk and face the void of going beyond where other people have gone who have any chance of being creative.
-- Howard Gardner
