Rick Rubin

Usually when I start a new project there's a fear of the unknown; maybe it's a band I've never been in the studio with before. People are so different. It's almost like you need to go through the process, discover and unlock what it is that makes that band that band. And a lot of times they don't know it.

I don't even know what a traditional producer is or does. I feel like the job is like being a coach, building good work habits and building trust. You want to get to a point where you can say anything and talk about anything. There needs to be a real connection.

I've always been an outsider. When I did magic, I was the only kid. When I worked with Johnny Cash, I was completely out of place in Nashville. And when I started Def Jam, I was the only white guy in the hip-hop world.

I used to carbo load. But then I ran my first marathon, actually on a whim. All I could think of was that I needed protein. I remember going to the grocery store and buying one of those roasted chickens. I remember downing a bunch of that and, yes, I had some carbs, but that's what I felt I needed.

As England manager I always felt we needed an extra man in midfield to retain the ball, but that was more as an attacking ploy to help create opportunities. It came from my experience playing international football in a 4-4-2 and spending half my time chasing the ball.
