Just listen to what Mr. [Donald] Trump has to say and make your own judgment with respect to how confident you feel about his ability to manage things like our nuclear triad.

We are reminded that, in the fleeting time we have on this Earth, what matters is not wealth, or status, or power, or fame, but rather how well we have loved and what small part we have played in making the lives of other people better.

You know, I think that we are going to be OK. Look, Malia is 10, so three years from now she is 13. Who knows what happens to teenagers?

My particular worries on any given day - how I'm doing in the polls or what somebody is saying about me... for good or for ill - isn't particularly relevant. What is relevant is: What am I building that lasts?

We reward people a lot for being rich, for being famous, for being cute, for being thin... one of the values I think we need to instill in our country, in our children, is a sense of 'usefulness', in other words, are we useful, are we making other peoples' lives a little bit better?

Strong countries and strong presidents talk to their adversaries. That's what Kennedy did with Khrushchev. That's what Reagan did with Gorbachev. That's what Nixon did with Mao. I mean think about it. Iran, Cuba, Venezuela - these countries are tiny compared to the Soviet Union. They don't pose a serious threat to us the way the Soviet Union posed a threat to us. And yet we were willing to talk to the Soviet Union at the time when they were saying we're going to wipe you off the planet.

I'm personally very grateful to my many friends in the Greek-American community, sons and daughters of Greece who have found success in every walk of American life.
