If you can get things done, then this counts for a lot. I know people who are geniuses and polymaths -- the kind of guys who do the calculus to optimize patterns for making their own juggling balls as a leisure activity. That doesn't mean that they are the best at getting things done though.

Be able to get things done. Be good at taking into account what you don't know. Know how to cooperate and delegate. This is the stuff that's most useful.
