The ideals and the values of the United States inspired the entire world. I don't think any of us can say that our standing in the world now, the way children around the world look at the United States, is the same. And part of what we need to do is to send a message to the world that we are going to invest in issues like education, we are going to invest in issues that relate to how ordinary people are able to live out their dreams. And that is something that I'm going to be committed to as president of the United States.

What I consistently say to young people - I say it in the United States, but I'll say it here in Germany and across Europe: Do not take for granted our systems of government and our way of life. I think there is a tendency, because we have lived in an era that has been largely stable and peaceful, at least in advanced countries, where living standards have generally gone up, there is a tendency I think to assume that that's always the case.

The Balkanization of the media means that nobody is having a single conversation with a single set of agreed-upon facts and assumptions the way you had as recently as the 90s.

I want every young man who sees me to know that I'm not that different from them. I wasn't born into wealth. I wasn't born into fame. I made a lot of mistakes - but I kept at it.

My liberty depends on you being free, too.

We could come together, Democrats and Republicans, to find practical, commonsense solutions to health care, to education, to energy issues, because although I'm a proud Democrat, I'm a prouder American. And I think all of us believe, regardless of our party affiliations, that this is a critical time, where we've got to solve big problems.

Our planet is changing in ways that will have profound impacts on all of humankind.
