Before, I was really passive, all I cared about was being in love with my boyfriend. I didn't have any creative power, nothing. I don't know that person any more.

It's superfun being a mom, but it's hard too.

I don't have a strong sense of self-worth unless I'm doing something.

Music has this emotional thing to it, and it touches people in crazy ways. The power of having that power is something that, once you have it, you don't want it to ever end.

It feels like the more I'm out there in the public eye, the more criticism I get. You need to have confidence - that's what it takes to walk out there and sing a song in front of a huge group of people.

Now I'm a wife and a mother of two. It's a really different role. I always referred to No Doubt as a marriage, because that's what it's like to be together for so long and go through what we've been through. I can't really have that relationship with them anymore.

Working with (new collaborators) and letting people in to try new melodies and new lyrical ideas was very hard.
