I think, as you get older, that's when your ambitions become "peculiar".

I think that where I've gotten frustrated during the course of my presidency has never been because I was getting pushed too hard by activists to see the justness of a cause or the essence of an issue.

I make no apologies for being reasonable.

We may come from different places and have different stories, but we share common hopes, and one very American dream.

I found during the course of my political career on the national scene there's a point where the vanity burns away and you've had your fill of your name in the papers, or big adoring crowds, or the exercise of power. And for me that happened fairly quickly. And then you are really focused on: What am I going to get done with this strange privilege that's been granted to me? How do I make myself worthy of it?

You could analyze me and say that my father leaving and being absent was a motivator for early ambition, trying to prove myself to this apparition who had vanished. You could argue that me being a mixed kid in a place where there weren't a lot of black kids around might have spurred on my ambitions. You could go through a whole litany of things that sparked me wanting to do something important.

That's where peace begins - not just in the plans of leaders, but in the hearts of people. Not just in some carefully designed process, but in the daily connections - that sense of empathy that takes place among those who live together in this land and in this sacred city of Jerusalem.
