Sophie Ellis-Bextor

Philately is normally a boys' hobby but for some reason it was in vogue at my junior school. Between the ages of eight and ten I collected avidly. I'd pore over my Stanley Gibbons book, obsessively checking my collection's value. I always hoped I'd stumble across a really valuable one, a Penny Black or an Inverted Jenny, but it wasn't to be.

The thing about dancing - what it taught me all those years - is it gives you an amazing sense of discipline in forcing yourself to do things that you know are good for you but you don't really want to do.

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.
