What actually interests me now, as I get older, is just narrative writing, telling a story. In a way that is always fiction, even when it’s memoir, or autobiography, or biography, or history; there is what actually happened, which is a total enigma, and then there is the story that people make out of it. It’s never really true. It’s always “made up.”
That having been said, there is a different kind of freedom to just totally making something up, out of nothing, with no reference to what supposedly happened. No other kind of writing is as interesting as writing a novel.
