The recently beautifully married Winchester Whisperer has a lovely Eastern tale today which only goes to reinforce my view that it is the flaw that makes the genius, or inspires the leap of imagination. There was a wonderful sci-fi book I read years ago about an enclosed city that every 20 years or so produced one flawed person. Over the eon's that sporadic being had not managed to get people out into the world. Of course, there would be no story unless the one in it actually did get people out and about.
Which he did.
