Anne-Marie Duff

I was desperately shy when I was wee. Totally lacked confidence socially. When I look back at school photographs, I'm always the one shrinking in the back. What I really wanted to do was become a writer, and I don't think the residue of that has ever gone away. I still feel the ultimate achievement would be to write a novel.

I think it helps to have a good old-fashioned trajectory, plodding along. Obviously one has an ego and it's really easy to have that ego tickled, but what helps me get through the night is if I concentrate on just quality of work so that I don't panic about my profile.

There are clearly many good politicians who are guided by religious belief, so the mix can work. But there's a line to be drawn. It would be hugely dangerous for a country's laws to be set by the scriptures, and particularly those of the expansionist religions.

When I have a creative insight, there is a high. I think back in the day, I made music as much as I did because it made me feel so good. I think you could argue that there is a creative addiction - but, you know, the healthy kind.
