There're some places that are more difficult or dangerous to navigate and I wouldn't look forward to going back. Like I'd much rather go back to Afghanistan - which fascinates me - quicker than I'd go back to spend a week walking around Nairobi, Kenya, which is a great and easy way to get yourself killed.

I have always thought that change you can see and feel is best.

I'm actually on the Twitter like all those crazy young kids are, and if I'm going to do an in-store appearance or I post something on my website, I tweet these followers, a word I don't like so much, and over 50,000 people go, like, 'Okay, I got it.'

The Wacken festival started more than 20 years ago with just a few hundred people in attendance. Tickets now sell out before the lineup is announced.

I have been restless for as long as I can remember.

I find it takes a lot of strength to endure myself.

Creating problems is easy. We do it all the time. Finding solutions, ones that last and produce good results, requires guts and care.
