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.

With learning lines, before I had Alfie, I'd put it off and think, 'Oh, I'll just have a glass of wine and then do it later,' but when you've finally got a child to bed and you know you've only got an hour, then you achieve so much.
