For a lot of pop performers, fame and celebrity is part of the job. But for singer-songwriters, no one really cares.

YouTube was really good for building a kind of core, loyal fanbase. I didn't want to be a YouTube artist as such. I mean, there are people who are able to release albums and live off YouTube, but I felt - and not in an arrogant way - that I could be commercial and credible if I really put my mind to it.

Labels fund things and have resources for you to use. But just because you sign doesn't mean you sign yourself away so they can then tell you what to do. You need to have a plan yourself before they do.

I'm really busy, but I don't feel like I'm missing out on anything.

Part of me feels like when you had a lot of success in your teens and 20s, it gets harder for you in your 30s because people are so attached to you as this ingenue. So even though you're older, they still think of you as that girl - that waifish young girl. And so it was sort of like a struggle.

Britain is one of the world's most open economies. More dependent on trade than any other major country. Our success depends on our competitiveness and our competitiveness depends on raising our productivity, as our competitors are raising theirs.

I hate the idea of success robbing you of your private life.

Being able to compete against the best, having success against the best, and to be included with the best - that's something I really relished whenever I got on the court.
