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.
We'll continue to speak out in a respectful way; never challenging somebody's love for America when you criticize their strategies or their point of view.
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.
That's one of our biggest challenges is finding out how to do that. There are times when you have to scale back. You might be performing on a five-by-five stage in front of 12 people. That's an exaggeration but there are times when you have to turn the corner and do an acoustic set.
