I have known writers who said they only ever wrote a single draft. The one who said he always got it right the first time I have never been sure if I believed him (that is, whether I believed that he felt it was always right the first time--others might have a different opinion of whether he got it right at all--or whether he was joking, which I wouldn't put past him).
Could this be me...?
Every novel I've had published since and including Hairy London, but not including Beautiful Intelligence, was a first draft. However I'm not saying they were necessarily right first time; that's a different thing...
I should stress though that I write my first draft in a particular way, that not everybody has the luxury of doing. For the duration of the writing I "live" the novel, not attending to anything else (including children - me & my ex never had any), which allows me to get that crucial, magical first draft down as completely as possible. Then I do polishing & honing, then it gets sent to my editor. He always comes back with points to change. A few times they're big points - for instance, in The Autist, he brilliantly suggested a change in the order of the first six chapters.
What I want to do is convey to my readers the magic I feel when discovering my novel for the first time. I find I lose that magic if there's a second draft. My intensive way of writing means I can capture the magic as completely as possible. It's a high risk strategy, though, so I don't recommend it!
