I'm not hopeful about America, and I'm not hopeful about the world, no. Life goes on and, for those of us who are lucky, there's a great deal to enjoy in it. But will things get better for most people? I don't know. I don't see the evidence.

I often say I've spent more time with photography than I have with literature just in terms of hours.

Still, there's that faint glimmer of hope we feel when we sense, in other people, the same kind of attentiveness to life that we take comfort in. Why else would anyone watch Haneke films or read Sebald? The material is grim, but it's redeemed by the quality of the attention.

Each time I caught sight of geese swooping in formation across the sky, I wondered how our life below might look from their perspective, and imagined that, were they ever to indulge in such speculation, the high-rises might seem to them like firs massed in a grove.

I became aware of just how fleeting the sense of happiness was, and how flimsy its basis: a warm restaurant after having come in from the rain, the smell of food and wine, interesting conversation, daylight falling weakly on the polished cherrywood of the tables. It took so little to move the mood from one level to another, as one might push pieces on a chessboard. Even to be aware of this, in the midst of a happy moment, was to push one of those pieces, and to become slightly less happy.

Perhaps this is what we mean by sanity: that, whatever our self-admitted eccentricities might be, we are not villains of our own stories.

Oh, I love labels, as long as they are numerous. I'm an American writer. I'm a Nigerian writer. I'm a Nigerian American writer. I'm an African writer. I'm a Yoruba writer. I'm an African American writer. I'm a writer who's been strongly influenced by European precedents. I'm a writer who feels very close to literary practice in India - which I go to quite often - and to writers over there.
