I'm a very slow worker. Even once it's typed up, there'll be layers of changes and additions and corrections. I hated going over things when I was at school. I'd just sit and let it pour out, and if I'd been asked to redraft it, it would have got staler, and worse . But now I enjoy nitpicking till it's absolutely the best I can do.
Some books take over a year.
Short books for young readers take just weeks or months. Not having constant compromises in my work life that most people have. I write the books for me . Then hope there are readers out there who like the same sorts of books I do. When I was very young, Enid Blyton.
