I'm never nervous when I go to meet heads of state. I feel they should be nervous, because they are the ones who'll be held accountable for the lives their decisions will impact the most.

As a rock star, I have two instincts, I want to have fun, and I want to change the world. I have a chance to do both.

In my view, the only thing worse than a rock star is a rock star with a conscience.

I'm a musician. I write songs. I just hope when the day is done I've been able to tear a little corner off of the darkness.

You know, God has some really weird kids, and I find it hard to be in their company most of the time.

Stop asking God to bless what you're doing. Find out what God's doing. It's already blessed.

The great music for so many artists - the Beatles, the Rolling Stones - was always at the moment when they were closest to pop. It would be easy for U2 to go off and have a concept album, but I want us to stay in the pop fray.
