Yes, one uses what one knows, but autobiography means something else. I should never be able to write a real autobiography; I always end by falsifying and fictionalizing—I’m a liar, in fact. That means I’m a novelist, after all. I write about what I know.
Everything is what it is, that's all. If we keep attaching meanings and mysteries to everything we perceive, everything we see that is, and to everything that goes on inside us, we are bound to go crazy sooner or later, I thought.
