I'm maybe not so anxious to be a successful pop artist. Of course I want people to like my music, but I know what the price of success can be, too. Basically, I'm happy as long as I can keep my freedom, so I'm so happy with the way things are at the moment. I get to be hands-on with details in every aspect of what I'm doing, but I also get to perform for a big audience.

Having access to mobile phones and being able to document your own life brings people together. Technology has a lot to do with how the world is developing at the moment because there are very raw and pure and primal emotions that people are communicating to each other over the Internet. It's like our new feathers, our new face paint. We're still trying to find love and friendship and cool music, but now it's over the Internet.

I wondered what things what things became when you no longer needed them, and I wondered what the future would hold once we'd gotten past our personal tragedies and proven them ultimately survivable.

All the big pop acts that I've been into over the years - whether it's ABBA or Prince - managed to combine amazing melodies and honest human emotion. But coming out of the super-super-commerical pop industry in the 90s, maybe people forgot about the fact that pop music can do both of those things.

Activists are cultural artists. They envision a world that does not yet exist, and then take action to create that world.'

So don't stop moving forward. For a while, you may feel as though you're taking two steps forward, one step back. And there may be some personal heartache along the way. But when you look your little ones in the eye, you will find your voice and take a stand for them. We are their voices. And we must have the courage to stand up for them, whatever the odds or however powerful the opposition might be.

Sometimes I think that everyone has a tragedy waiting for them, that the people buying milk in their pajamas or picking their noses at stoplights could be only moments away from disaster. That everyone's life, no matter how unremarkable, has a moment when it will become extraordinary - a single encounter after which everything that really matters will happen.
