Harriet Walter

I'm not very good at going to sleep, and that's probably my worst problem. I don't need much more than seven and a half hours, but I probably get six. I take all my problems to bed with me and fret. I can't switch off.

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.
