I think that I've learned some lessons over the past four years, and the most important lesson I've learned is that you can't change Washington from the inside. You can only change it from the outside. That's how I got elected and that's how the big accomplishments like health care got done – was because we mobilized the American people to speak out. That's how we were able to cut taxes for middle class families. So, something that I'd really like to concentrate on in my second term is being in a much more constant conversation with the American people, so that they can put pressure on Congress to move some of these issues forward.
