There's a booming, rotating, never sleeping city in the center of my brain and no body can come in and I can't escape. I have a strange sense of pride that my brain works that way, but I'm also terrified of what would happen if I ever tried to think in another way.

Before Guadalcanal the enemy advanced at his pleasure - after Guadalcanal he retreated at ours.

I wake up every day and think about what I am to other people. What I am to the people I employ, who depend on me to wake up and do my job that day and keep this career going? I think about what I am to the kids who listen to my music and all the other people involved in this project.
