That's something I loved growing up - the other team yelling, hyped, student section, all of that gets me going.

The competitive spirit and the way we worked hard growing up came naturally to me from my family.

My whole family growing up played sports, so I'm definitely from a strong sporting background.

Puma does a really good job with its athletes and providing what we want.

It's funny - some producers ask me, 'Man, how do you work on a Bieber record? That would kill my career.' I can work on any record there is as long as they are good records and you're pushing things forward.

From the time I left the Marine Corps after serving as an infantry platoon and company commander in Vietnam, I decided that I would focus on immediate goals that inspired me to devote all of my energy to them, rather than putting together the more cautious and traditional building blocks of a predictable career.

I've accomplished everything I ever wanted to do in my career.

It's what is strange about doing a job that is also the thing you love, the thing you feel passionate about. People get to the point where they're burned out and disillusioned by the whole thing because when things aren't going well at work it also means they aren't going well in your heart, in your soul. They're all wrapped up together.
