I love what I'm doing most of the time, but it's hard work. People only see your albums in the charts. They see us at award shows and after-show parties. They don't know about your doubts, the hard work that goes in.

I am really addicted to music.

By just passing through things, I continue to slightly limit myself. I want the jobs that don't say that much. I'm often the stepping stone or the conduit from one thing to another. I love the idea of existing in a film and growing and having bigger arcs, and being in scenes where you're just being, as opposed to talking. That' one of my ambitions, lying ahead.

Any reaction is better than none.

It's a very selfish time. When I'm here at home, my responsibilities are far greater. I'm forced to be way more selfless. My priorities are so far down the list that it's hard to see them. And yet, when I'm on tour, I basically have to get the show right, every night, but the days are really constructed around selfish activities for self-improvement, or not. That's where I feel guilty because I know that life is going on full-speed when I'm not around.

Dub and reggae... I play that a lot around the house.

It's like a relay race of being ignored. It is really challenging, but whenever I get asked that stuff, I feel really self-conscious about it. I feel really lucky because we have a lot of help. When I first began to be a dad with Gwen [Stefani], I was amazed at what she went through.
