When I was 25, Abba was formed. After Abba I made three solo albums. Maybe I have been productive enough.
I hope in my books I help children to see their strengths, and show them I have some idea of what they may occasionally be going through. Especially at tricky moments when it is easier to go back and evade things rather than go forwards and confront them.
I kind of got my big break with 'The Princess Diaries' and during the press rounds for that everyone asked me: 'Did you always want to be a princess growing up?' And the truth was, no I wanted to be Catwoman.
