Part of Obama's persona is self-reliance. He's calm he's cool he's self-possessed. In many ways he has tried to define himself in opposition to Clinton's sometimes needy often undisciplined emotionalism.

It's interesting to feel the pressure of having to be outgoing because I think in general as a human being I'm pessimistic and introverted. But it's cool because it's a whole different side of me and I impress myself. Even at times when I think that there's no possible way that I can be engaging I'll suddenly pull it out and impress myself.

I think sometimes I guess you see records say you want to get there and use that as motivation. In a way it's kind of cool if there is a possibility to rewrite history and be up there with the greats of Olympic history.

Sometimes just when I say hello the right way I'm like 'Whoa I'm so cool.'

I've never had Internet access. Actually I have looked at things on other people's computers as a bystander. A few times in my life I've opened email accounts twice actually but it's something I don't want in my life right now.

Our lives sometimes depend on computers performing as predicted.

I get hired to hack into computers now and sometimes it's actually easier than it was years ago.

One of the most feared expressions in modern times is 'The computer is down.'

I wrote somewhere during the Cold War that I sometimes wish the Iron Curtain were much taller than it is so that you could see whether the development of science with no communication was parallel on the two sides. In this case it certainly wasn't.

I didn't have a lot of communication with Elvis. You had to go through a barricade to get to Elvis. It was people hanging on every word and I felt very uncomfortable a lot of times.
