We've been a country that's been fortunate to be protected by two oceans, to not have serious attacks on our territory for most of our history. And we were unfortunately reminded in a very devastating way of our vulnerability.

The sooner you learn that life is not fair, the better off you'll be, because you'll spend less time railing against life's unfairness and feeling aggrieved and entitled, and more time figuring out how to maximize your assets, and your talents and how to deal with things that you're not very good at.

It's so much a part of me that it's almost hard to describe myself in the absence of it. I know that for me it means asking for guidance, and that in the toughest times there's a personal savior that I can rely on. And I'm very grateful to my parents for giving me that.

My mom was a teacher - I have the greatest respect for the profession - we need great teachers - not poor or mediocre ones.

I think America is still a bright, shining city on the hill - not because we're perfect but because we struggle in our imperfections every day.

Most of the people who were responsible for 9/11 are now in custody or have been killed. But there are others, and they plot and they plan, and they hope to pull it off again. And while we have to be right 100 percent of the time, they only have to be right once. So there's no way to overreact to that.

I think all of us have really got to redouble our efforts, first of all, to pay attention to the K-12 crisis. The sad fact is that I can look at your zip code and tell whether you're going to get a good education. That's not fair. And secondly, I hope that all of us who were fortunate enough to have benefited will put our time, our resources and our efforts into making sure that kids, particularly kids without means, have a way to achieve.
