We have the potential to help people out of poverty, out of disease, out of slavery and out of conflict. Too often we turn the other way because we think there's nothing we can do.

Something I've learned from people like U2, the Stones and Lenny Kravitz is that the grind of live shows is so necessary [to build your career].

I was just talking to Bono the other day, and he was like, "Are you doing shows?" I've just been off the road for a month-and-a-half, and he was like, "You lucky girl."

Prayer keeps me centered.

If I know everything around the situation, all the facts, I feel like I can handle just about anything.

I believe if you can find something to give back to, your soul will feel fulfilled in a very powerful way.

Love will come find you, just to remind you of who you are.
