Not all coincidence has to be loaded with meaning. Sometimes, things simply recur because that's how it is in life, that's how the mood gets in. It's good to subtly overdo it too, as Nabokov does, as Sebald does. It's a good way to intensify that region of localized weather that we call a novel.

Perhaps this is what we mean by sanity: that, whatever our self-admitted eccentricities might be, we are not the villains of our own stories. In fact, it is quite the contrary: we play, and only play, the hero, and in the swirl of other people's stories, insofar as these stories concern us at all, we are never less than heroic.

Things don't go away just because you choose to forget them.

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.

Note-taking is important to me: a week's worth of reading notes (or "thoughts I had in the shower" notes) is cumulatively more interesting than anything I might be able to come up with on a single given day.

It is a work of psychogeography, albeit in a less explicit sense than Iain Sinclair's or Will Self's. It had to be fiction though, because I needed that freedom of including whatever belonged, and cutting out whatever didn't. The main fiction in it was matching Julius' generous and self-concealing character to New York's generous and self-concealing character. I think this also adds to my answer about New York's personality in the book.

What's interesting about Twitter is the unmediatedness of it, the directness of it. I'm on a train somewhere in New York and I send out a tweet. Somebody sitting at dinner in Bombay checks their phone and they see it.
