I've written what and when I want to. It's been about expressing myself. But with the degree, I had to learn to do everything in a very specific, disciplined way. I am very disciplined, but this demanded a totally different kind of discipline. A real challenge.

When I was younger I was obsessed with writing, so even if I wanted to listen, I didnt have time.

You don't have to be rich and famous. You just have to be an ordinary person, doing extraordinary things. I'd like more people to know that it's there. Women's achievements still aren't recognised enough in many areas.

I am constantly being told that I have been a big influence for many people, including other musicians.

Writing music is just something that I was born to do.

Inspiration doesn't really work like that - you're not looking out for it. Inspiration is something that tends to capture you rather than you capture it.

So if you're on tour for eight months, a year... or whatever it is you definitely don't want arguments and I'm happy to say that I've always had a really nice bunch of people around me all the time.
