Why We Write

I found this explanation by Andrea Barrett at "The Dish":

I’ve never known a writer who didn’t feel ill at ease in the world. Have you? We all feel unhoused in some sense. That’s part of why we write. We feel we don’t fit in, that this world is not our world, that though we may move in it, we’re not of it. Different experiences in our lives may enforce or ameliorate that, but I think if they ameliorate it totally, we stop writing. You don’t need to write a novel if you feel at home in the world. We write about the world because it doesn’t make sense to us. Through writing, maybe we can penetrate it, elucidate it, somehow make it comprehensible. If I had ever found the place where I was perfectly at home, who knows what I would have done? Maybe I would have been a biologist after all.
