I seem to have very polite fans, not fanatical ones.

It's much easier to write when you're sad. But you can end up isolated and depressed because you almost need to put yourself in that situation to have that angst to write from.

Ignore reality, there's nothing you can do about it.

Happy songs are very difficult to write. How many truly great upbeat songs are there?

I can understand why some people might look at me and say, 'What's she got to be depressed about?' I get that a lot in Britain, where mental health issues seem to be a big taboo.

I'm such a chameleon. I never get bored.

Saving animals is as simple as choosing synthetic alternatives instead of real fur.

If I start feeling down I'll gorge myself on pasta. That usually does the trick. It's the Italian blood in me.

Enjoy every moment: you never know when things might change.

It was only cool to have blond hair and be a surfer chick [in Sydney]. I could learn how to surf, but I still looked Italian. It took me a long time to realize that was a good thing.

Isolation is a big part of songwriting.

What's done cannot be undone.

Courage is to walk hand in hand with the fear!

What you work for, you will receive.

You are not alone with a guy until you are a proper age. You don't go to certain levels with men until you are married or you have a certain relationship.

But it is really, really fun to just change it up some and to absolutely be a very small spoke on a big wheel, and to just be a part of that and contribute to something that people can enjoy.

I know the police cause you trouble They cause trouble everywhere But when you die and go to Heaven You'll find no policemen there.

The insidiousness of science lies in its claim to be not a subject, but a method.

I'm completely aware of the fact that I'm a control freak.

Dairy products are not good for a singer.
