Isaiah Berlin once said that there are two kinds of writers, hedgehogs and foxes. He said the fox knows many things, the hedgehog knows just one thing. So Shakespeare is a typical fox; Tolstoy and Dostoyevsky are typical hedgehogs. Now, I'm a typical hedgehog. I know just one thing, and I repeat it over and over again. I try to approach it from different angles to make it look different, but it's the same thing.
