Some of my relatives held on to imagined memories the way homeless people hold onto lottery tickets. Nostalgia was their crack cocaine, if you will, and my childhood was littered with the consequences of their addiction : unserviceable debts, squabbles over inheritances, the odd alcoholic or suicide.

I think walking is very useful, like sleeping and dreaming, as something that's important to my ability to write.

We are all refugees from our childhoods. And so we turn, among other things, to stories. To write a story, to read a story, is to be a refugee from the state of refugees. Writers and readers seek a solution to the problem that time passes, that those who have gone are gone and those who will go, which is to say every one of us, will go. For there was a moment when anything was possible. And there will be a moment when nothing is possible. But in between we can create.

I like the idea of an open, international London that thrives on attracting hard-working, talented people but has the confidence to tell them they must play by the same rules as everyone else.

In a world of intrusive technology, we must engage in a kind of struggle if we wish to sustain moments of solitude. E-reading opens the door to distraction. It invites connectivity and clicking and purchasing. The closed network of a printed book, on the other hand, seems to offer greater serenity. It harks back to a pre-jacked-in age. Cloth, paper, ink: For these read helmet, cuirass, shield. They afford a degree of protection and make possible a less intermediated, less fractured experience. They guard our aloneness. That is why I love them, and why I read printed books still.

Chance plays a powerful role in every life - our brains and personalities are just chemical soup, after all; a few drops here or there matter enormously - but consequences often become more serious as income levels go down.

My aunt used to say, "It's between me and my god; it's got nothing to do with you." It was a good enough answer for me as a snot-nosed college kid angling for a religious debate, and I still think it's a good way of putting it.
