Each path to knowledge involves different rules and these rules are not interchangeable.

For the sake of our security, our economy and our planet, we must have the courage and commitment to change.

Building on our Young South-east Asian Leaders Initiative, I'm hopeful that we can continue expand the ties and cooperation between our young people and students.

I am absolutely certain that generations from now, we will be able to look back and tell our children that this was the moment when we began to provide care for the sick and good jobs to the jobless; this was the moment when the rise of the oceans began to slow and our planet began to heal; this was the moment when we ended a war and secured our nation and restored our image as the last, best hope on earth. This was the moment - this was the time - when we came together to remake this great nation so that it may always reflect our very best selves and our highest ideals.

Let me tell you another place to look for some savings. We are currently spending $10 billion a month in Iraq when they have a $79 billion surplus. It seems to me that if we're going to be strong at home as well as strong abroad, that we have to look at bringing that war to a close.

If poverty is a disease that infects the entire community in the form of unemployment and violence, failing schools and broken homes, then we can't just treat those symptoms in isolation . We have to heal that entire community.
