I would try to keep myself going by inventing games, and I would sing songs, a song beginning with “A,” “Always.” “Because,” “Charmaine,” “Daisy,” go through the alphabet. ... I would try to remember the states in the United States of America.

My favorite method is stopping everything for a moment. It’s amazing how difficult I find it these days to simply sit quietly.

First of all, you learn to manage stress. You learn to live with stress. I mean, stress is there all the time. There’s no question about it. It’s in the morning. It’s at night. It’s at 3:00 in the morning, but you need to learn how to manage stress. Sometimes it’s more difficult than others, but you try to distract yourself. Whenever I have the chance, I like to go and have a round of golf. I have a passion for modern art. I have a passion for antique carpets, classical music. To me, these are distractions, and sometimes my wife, she think I’m obsessed with these little things, but I tell her it is my way of distracting myself from just constantly continuing about my work. But the stress is there. But sometimes, the euphoria you get from a sense of achievement in many ways compensates all the stress you had for a year or two.

The kind of hope I often think about (especially in situations that are particularly hopeless, such as prison) I understand above all as a state of mind, not a state of the world. Either we have hope within us, or we don't.

I'm writing with a clear lesbian agenda in the novels. It's right there at the heart of the books.

Writing fiction is not “self-­expression” or “therapy”. Novels are for readers, and writing them means the crafty, patient, selfless construction of effects. I think of my novels as being something like fairground rides: my job is to strap the reader into their car at the start of chapter one, then trundle and whizz them through scenes and surprises, on a carefully planned route, and at a finely engineered pace.

Treat writing as a job. Be disciplined. Lots of writers get a bit OCD-ish about this. Graham Greene famously wrote 500 words a day. Jean Plaidy managed 5,000 before lunch, then spent the afternoon answering fan mail. My minimum is 1,000 words a day – which is sometimes easy to achieve, and is sometimes, frankly, like shitting a brick, but I will make myself stay at my desk until I’ve got there, because I know that by doing that I am inching the book forward. Those 1,000 words might well be rubbish – they often are. But then, it is always easier to return to rubbish words at a later date and make them better.
