If everything really does get better, the way everyone claims, then happiness should be graphable. But that's crap, because better isn't quantifiable.

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.

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.

The music industry is such a huge machine. There are still a lot of good people in it, but the character of the industry and the culture of the industry is very fast.

I always felt like I could combine good pop songs that are easy for people to like with a real person and a real mind and integrity. So maybe I bring people into that pop world who don't usually find themselves there because there's not enough stuff for them to get excited about otherwise. I try to be genuine. I try to be real. It's such a subjective thing, but I try to convey an emotion.

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

Even if I'm sad, dancing is a way to let stuff out.
