It may be a hundred-year battle to turn around our industries and finally get everyone living on sustainable energy with technology that can keep our lives comfortable. If that's the case, the first 20 years of the shift have actually done a lot to support that. But there's still a long way to go, and judging by the state of the environment, we don't have that kind of time.

It was a very bizarre experience for me, to get the songs together, go in there, and try to deliver them as I would perhaps in a live setting. But I realized that I couldn't take on that coffeehouse style that I came from and go in there and burn it up.

My parents dreaded the fact that I was changing my life to do this, but I just kept doing it.

What I get on a yoga mat, and from a yoga teacher, has been more beneficial onstage than any other workshop I've ever done. And it starts with that breath; it starts with getting out of my head and really just slowing the system down and being in a true present moment with each and every breath. That then allows me to be a more balanced and focused individual onstage.

You come to realize that only one person can tell you what's expected of you, and that's you.

Paul McCartney and John Lennon would often write a song a day, so I have the same workmanlike philosophy.

To create an album of 12 songs, I've got to write about 80 songs. Half of those are totally weird and rubbish.
