Write a book you'd like to read. If you wouldn't read it, why would anybody else? Don't write for a perceived audience or market. It may well have vanished by the time your book's ready.
Hilary MantelA sea-green sky: lamps blossoming white. This is marginal land: fields of strung wire, of treadless tyres in ditches, fridges dead on their backs, and starving ponies cropping the mud. It is a landscape running with outcasts and escapees, with Afghans, Turks and Kurds: with scapegoats, scarred with bottle and burn marks, limping from the cities with broken ribs. The life forms here are rejects, or anomalies: the cats tipped from speeding cars, and the Heathrow sheep, their fleece clotted with the stench of aviation fuel.
Hilary MantelIf you get stuck, get away from your desk. Take a walk, take a bath, go to sleep, make a pie, draw, listen to music, meditate, exercise; whatever you do, don't just stick there scowling at the problem. But don't make telephone calls or go to a party; if you do, other people's words will pour in where your lost words should be.
