I make myself suffer with a lot of self doubt.

If you're stuck in a situation that's painful or there's something that makes you angry, it can enable you to step back from your own experience of it and realize that this is just a part of what it is to be human. It can allow you to accept it a little bit more and make you feel like it's less unfair.

I have to say what I do is not easy and there are definitely moments where I feel inadequate to the tasks I've set for myself. And that's hard to feel - like you're giving your life to something and you can't really do it as well as you want to do it.

Being an artist is not exactly the most universally respected, or secure thing to do with your life. It can be frightening and you can feel that you're taking a lot of risks just with your own life, and your family's security. But the rewards outweigh those things.

Even if I'm doing a show and there's five people in the audience and the sound system is terrible - I mean, it's been a while but I've certainly done those kind of shows where it's just every conceivable thing is against you - you still have music. It's still something that's real whether there's five people in the audience or a hundred thousand people in the audience. And that's always been there for me.

I think I had a tendency to get stuck inside my head and go to some very dark places in my mind, and get stuck there. I couldn't see a way to get out.

If you listen to soul music, or R&B music, or Blues music, a lot of that came from church music and spiritual music, and music has always been a really really powerful tool that people have used to get them closer to God - whatever they define God as. And for me that's always been part of what drew me to it and keeps me coming back for more.
