"It's a weird thing, writing. Sometimes you can look out across what you're writing, and it's like looking out over a landscape on a glorious, clear summer's day. You can see every leaf on every tree, and hear the birdsong, and you know where you'll be going on your walk. And that's wonderful. Sometimes it's like driving through fog. You can't really see where you're going. You have just enough of the road in front of you to know that you're probably still on the road, and if you drive slowly and keep your headlamps lowered you'll still get where you were going. And that's hard while you're doing it, but satisfying at the end of a day like that, where you look down and you got 1500 words that didn't exist in that order down on paper, half of what you'd get on a good day, and you drove slowly, but you drove.
