There's something about losing friends, particularly young people, where it's not something that you get over. I don't believe there's a healing process.

I'm pretty critical, but I'm also pretty good at letting go once it's done. There's this existential argument that comes in, at some point, when you're over-thinking the songwriting process. There's no guarantee that the more time you spend or the more you concentrate on certain aspects that that's going to produce a better result, especially in the arts. Some of the most brilliant things that someone might do could happen in three minutes because it's something that just occurs to them.

I don't really go mountain biking per se, like a proper sport.

I had to teach myself to let go of the conventional rock way of playing guitar and singing. Some things you wouldn't expect to work, did and some things won't ever work.

There wasn't a key moment when I knew I wanted to quit.

When you're having a conversation with someone who, despite his brilliant medical career, says he's going to produce the film, you think, "How's he gonna do this? Is he insane, or is he really going to pull this off? It might be both." It's really amazing to see someone do what he's done.

I would hope that the future would have an international community that's not just bent on commerce, but that's focused on refugees, of all kinds and from all places. We don't know that won't happen in the U.S. someday. It literally could be a crisis from climate change, or anything. I think there needs to be a global focus on people taking care of people.
