“A restaurant on the moon could not have had less atmosphere.”

“The perfect life, the perfect lie, I realised after Christmas, is one which prevents you from doing that which you would ideally have done (painted, say, or written unpublishable poetry) but which, in fact, you have no wish to do. People need to feel that they have been thwarted by circumstances from pursuing the life which, had they led it, they would not have wanted; whereas the life they really want is precisely a compound of all those thwarting circumstances.”

“In the cramped confines of the toilet I had trouble getting out of my wet trousers, which clung to my legs like a drowning man. The new ones were quite complicated too in that they had more legs than a spider; either that or they didn't have enough legs to get mine into. The numbers failed to add up. Always there was one trouser leg too many or one of my legs was left over. From the outside it may have looked like a simple toilet, but once you were locked in here the most basic rules of arithmetic no longer held true.”

“We'd never seen anything as green as these rice paddies. It was not just the paddies themselves: the surrounding vegetation - foliage so dense the trees lost track of whose leaves were whose - was a rainbow coalition of one colour: green. There was an infinity of greens, rendered all the greener by splashes of red hibiscus and the herons floating past, so white and big it seemed as if sheets hung out to dry had suddenly taken wing. All other colours - even purple and black - were shades of green. Light and shade were degrees of green. Greenness, here, was less a colour than a colonising impulse. Everything was either already green - like a snake, bright as a blade of grass, sidling across the footpath - or in the process of becoming so. Statues of the Buddha were mossy, furred with green.”

“Have regrets. They are fuel. On the page they flare into desire.”

“Have more than one idea on the go at any one time. If it's a choice between writing a book and doing nothing I will always choose the latter. It's only if I have an idea for two books that I choose one rather than the other. I ­always have to feel that I'm bunking off from something.”

“Sometimes I think my ability to concentrate is being nibbled away by the internet; other times I think it's being gulped down in huge, Jaws-shaped chunks. In those quaint days before the internet, once you made it to your desk there wasn't much to distract you. You could sit there working or you could just sit there. Now you sit down and there's a universe of possibilities – many of them obscurely relevant to the work you should be getting on with – to tempt you. To think that I can be sitting here, trying to write something about Ingmar Bergman and, a moment later, on the merest whim, can be watching a clip from a Swedish documentary about Don Cherry – that is a miracle (albeit one with a very potent side-effect, namely that it's unlikely I'll ever have the patience to sit through an entire Bergman film again).Then there's the outsourcing of memory. From the age of 16, I got into the habit of memorising passages of poetry and compiling detailed indexes in the backs of books of prose. So if there was a passage I couldn't remember, I would spend hours going through my books, seeking it out. Now, in what TS Eliot, with great prescience, called "this twittering world", I just google the key phrase of the half-remembered quote. Which is great, but it's drained some of the purpose from my life.Exactly the same thing has happened now that it's possible to get hold of out-of-print books instantly on the web. That's great too. But one of the side incentives to travel was the hope that, in a bookstore in Oregon, I might finally track down a book I'd been wanting for years. All of this searching and tracking down was immensely time-consuming – but only in the way that being alive is time-consuming.”
