I think that, for a lot of us, the closer we get to showing people who we really are, that's where we feel the most uncomfortable, the most vulnerable. But it's also where the healthiest growth comes from. Like when I can really open myself up to someone and show someone who I really am, it's amazing when it happens.

I've been having a midlife crisis since I was four years old.

I can spend years studying and being in therapy and having a very analytic spiritual meditation practice, but without the emotional component, without the softening that comes with love and vulnerability, everything else I do is really just surface.

For me the most important issue is climate change because it in some ways trumps every other issue. Everything else we care about falls by the wayside if the Greenland ice shelf falls into the sea. And if suddenly sea levels rise 21 feet, everything we hold near and dear ceases to exist.

Who wakes up when they're worth £120million and says, 'I'm unhappy today but if only I had an extra £2million!'

If I'm walking down the street and someone stops me and says, "Oh! A song that you wrote meant a lot to me, and I listened to it after I went to my sister's funeral," that's when it hits me.

When you say 'failure,' that seems really dramatic, but a lot of failure is just really depressing and mundane. I remember the first time I ever played a concert in Italy. I played a venue that held 900 people, and I think five people showed up. It wasn't a big, 'John Carter of Mars' type failure. It wasn't dramatic; it was just depressing.
