So long as I'm the president, we will. I clearly see the challenge. I see the challenge of what these threats pose to our homeland, and I see the challenge of what these threats pose to the world.
Whenever I look at the history of presidents I deeply admire - the one thing that I'm always struck by is persistence. It's a quality that's underrated. Being able to plough through, being able to stay buoyant in the face of challenges.
As a matter of fact, it's in our interests that we help reformers across the Middle East achieve their objectives. This is the fundamental challenge of the 21st century.
You only have temporary curiosity, amusement, and challenges, but that does not necessarily mean you are really convinced that it's necessary or that it's not even worth to do it. It's just a way you have to set up some kind of activities to follow your instincts or your curiosities.
I always want to set myself a challenge by doing something no-one would expect me to do! But, having said that, I don't feel as a musician you can steer too far away from what you normally do.
