I spent a lot of time when I was president, trying to end wars, prevent killing, and promote understanding. What I have seen is that peace works better than conflict, and one of the best manifestations of it is in travel and tourism.

Our overriding environmental challenge tonight is the worldwide problem of climate change, global warming, the gathering crisis that requires worldwide action.

Today, many companies are reporting that their number one constraint on growth is the inability to hire workers with the necessary skills.

Effort, not ability, makes the biggest difference in achievement.

The good news is you can get a lot of information off the Internet for free and in a hurry.

I believe we can do much more to adapt to the structural changes in the global economy, get high-end manufacturing back here, set up clusters of economic activity where you have, among other things, continuous retraining of people well into their middle years so they never become irrelevant to the current job market.

I think that the responsibility that the Democrats had may rest more in resisting any efforts by Republicans in the Congress, or by me when I was President, to put some standards and tighten up a little on Fannie Mae and Freddie Mac.
