America is tough for rock music. Rock n' roll used to be the main music for the youth, and it's not so much anymore. It's hip-hop and stuff.

I don't take breaks, man. In the past, I used to spend my free time getting in trouble, and now I spend it working on my music. If I'm not playing drums with my cover band, Chevy Metal, I'm working on songs for myself.

In the Foo Fighters, my main job is to be the drummer, and that's enough.

I've been lucky enough to have fulfilled so many ambitions, and gone way past anything I ever thought I would do. I could never have imagined the career that I've had with the Foo Fighters - playing stadiums and having songs on the radio. It's amazing, and my goal is really just to carry on playing.

Winning Le Mans didn't change my career, but it definitely gave me a boost.

Perhaps I will stay in Chicago and operate on human beings instead of on dogs. From a business standpoint, it would be excellent. But, as I hate medical practice, I would like better to make little money in doing scientific work than a great deal in doing surgical operations.

It took me eight books to finally be at a point in my career where I could come out with a book and say, 'This is meant to be a funny book,' and we didn't have to make any bones about it.

Take any job in a growing, exciting company. You'll learn so much.
