I sacrifice in my love life and my social life, but those things will be there in three or four years. This is a really important time in my life. I can't just be the girl who sang 'I Kissed a Girl.' I have to leave a legacy.

My father left his piano at the house when he left, and I wasn't allowed to play it when he was there because I wasn't as good as him. So when he left, I was determined to get as good as him, and I taught myself how to play music, and I just stuck with it, and I did it all the time.

I write songs because that's the thing I chose to do. And I can't help writing them, that's a fact. Sometimes I felt as though you worked to justify your existence, but you don't; you work to exist, and vice versa, and that's it, really.

Music is what I breathe, what I love to do. It keeps me alive.

A lot of my songs are fantasy. I can dream up all kinds of things. That's the kind of world I live in. It's very sort of flamboyant, and that's the kind of way I write. I love it.

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.
