I don't believe in regrets. There are a few things I'd do differently, but I can't go back in time and redo them, however much I might wish to. All I can do is learn from past mistakes and move forward.

Book sales and teens reading is always a fantastic thing, but we should also be celebrating and consuming the huge wealth of U.K. and U.K.-based writing and illustrating talent. Authors such as Charlie Higson, Darren Shan, Holly Smale, Tanya Byrne, Catherine Johnson, Sophie Mckenzie, to name but a few.

If a child wants to read 'Twilight' over Middlemarch, they should be encouraged - the important thing is to get them reading in the first place.

I read a lot of highly unsuitable books for an 11-year-old. I was desperate to read as widely as possible. I thought, 'There are so many places I am never going to get the chance to visit, but I can if I read them.' And I did. I could go anywhere in the world - and off it - by reading.

If 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.
