The fact is that I am always thinking of something to build. A new book, radio show, plans for a trip somewhere. I am not a very happy person but I feel pretty even when I am working, so I guess that is how I am wired.

I have a house, I try to spend as little time in it as possible. Not always easy on the mind and body, but it's how I got myself to 80-plus countries. This kind of routine forces one to reinvent and improvise. The older I get, the more important this is to me.

If you listen to the way I speak and watch the way I conduct myself - there's nothing about me that's rock n' roll. It's like, 'Hello, I'm in a rock n' roll band'. 'No, you're a narc.'

Now, if someone wants to spit on me, I just roll up the window of my BMW 540i.

My laptop seems to know where I am, even if I don't. My cellphone asks me if I want directions to anywhere from the spot I am standing in. I buy a record online and Amazon.com sends me letters, telling me that people who bought what I bought also bought these other records.

But can a song stop a war? If Bob Marley and Bob Dylan couldn't do it, it can't be done.

I didn't want to work at Pizza Hut and I didn't want to join the Army. So I just decided to go out and be awesome.
