I am such a bad liar. I would like to lie, though.

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.

Erase the victim mentality. Remember you are capable of achieving greatness. If only you'd believe in your abilities to overcome. You are victorious. Celebrate the victory.

The cabin on the lake is nothing compared to my mansion in eternity!

Every artist was first an amateur.

Though the people support the government the government should not support the people.

At least half of my life's many mistakes can be safely put down to impetuosity: the other half derive from inertia.

I can go from blokey to girlie in 15 minutes and then I'm out the door. But that's the fastest I can do it. Becoming a woman takes work.

Free as air; that's what they say- "free as air". Now they bring me my air in an iron barrel.

We of America are especially fitted to visualize and to understand the marvellous transformation of a wilderness into a land of splendid cities.

It feels like it's the end of the world if you don't do well on your SATs.

You have a whole life in the outdoors, you realize you have a sense of responsibility to protect these wild places.
