A pet interest of mine is trying to better understand those who are considered geniuses. Malcolm Gladwell has an extremely interesting (of course) piece on the subject in the most recent New Yorker. He focuses mainly on the myth that all genius pours from a person easily and at an early age.
The article tells the story of those who struggled for decades to create great works of art. Focusing mainly on the writer Ben Fountain and the artist Cézanne. It's interesting to read about the personalities that bloom late and the support system needed for such a late bloom.
As an aside, Jonathan Safran Foer is mentioned and interviewed in the article as an example of the phenom (early genius). If you're interested more in him, I'd suggest listening to this interview on Slate.com
