Change is never easy, but always possible.

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?

I look forward to hosting Prime Minister Lee [Hsien Loong], whose friendship and partnership I appreciate very much and with whom I've worked throughout my administration. This will also be an opportunity for me to reciprocate the hospitality that the Prime Minister and the people of Singapore showed to me during my visit to Singapore for the APEC summit in 2009.

We will harness the sun and the winds and the soil to fuel our cars and run our factories.

America is a nation of immigrants. And so the question is, how do we make legal immigration faster, less bureaucratic, cut the red tape?

I think I have a pretty good take on popular culture that maybe makes up for the fact that I'm not a sound-bite politician for the nightly news.

Now, in practice, in daily social interactions, etc., there may be all kinds of biases and prejudices that are unspoken, that people aren't aware of, that affect who's hired, and who gets loans, and how kids are treated in school. But it's a powerful thing if you have on your side an idea that the overwhelming majority of people believe in because that's how you can build a consensus that's lasting.
