We are the change we have been waiting for. - Barack Obama

You can't be complacent and accept the world just as it is. You have to imagine what the world might be and then push and work toward that future. Progress requires that you honestly confront the dark corners of our own past; extend rights and opportunities to more of your citizens; see the differences and diversity of this country as a strength, just as we in America try to see the diversity of our country as a strength and not a weakness. So you can choose the path to progress, but it requires making some important choices.

There’s already an evolution taking place inside of Cuba, a generational change. Many suggested that I come here and ask the people of Cuba to tear something down -- but I’m appealing to the young people of Cuba who will lift something up, build something new.

With these thoughts came another: Was that unity of effort, that sense of common purpose, possible only when the goal involved killing a terrorist? The question nagged at me. For all the pride and satisfaction I took in the success of our mission in Abbottabad, the truth was that I hadn't felt the same exuberance as I had on the night the health care bill passed. I found myself imagining what America might look like if we could rally the country so that our government brought the same level of expertise and determination to educating our children or housing the homeless as it had to getting bin Laden; if we could apply the same persistence and resources to reducing poverty or curbing greenhouse gases or making sure every family had access to decent day care. I knew that even my own staff would dismiss these notions as utopian. And the fact that this was the case, the fact that we could no longer imagine uniting the country around anything other than thwarting attacks and defeating external enemies, I took as a measure of how far my presidency still fell short of what I wanted it to be - and how much work I had left to do.
