There are always going to be some complications.

With patient and firm determination, I am going to press on for jobs. I'm going to press on for equality. I'm going to press on for the sake of our children. I'm going to press on for the sake of all those families who are struggling right now. I don't have time to feel sorry for myself. I don't have time to complain. I am going to press on.

So don't get cynical. Cynicism didn't put a man on the moon. Cynicism has never won a war, or cured a disease, or built a business, or fed a young mind. Cynicism is a choice. And hope will always be a better choice.

Here at home, we will strengthen our defenses but not succumb to a siege mentality that sacrifices the open society and liberties and values that we cherish as Americans, because great and proud nations don't hunker down and hide behind walls of suspicion and mistrust.

One of the gratifying things, I think, about the end of my presidency even though admittedly my successor ran against a lot of what we stood for, is when you look at the individual issues and the progress that we've made on a lot of those issues, we got the support of a pretty decent majority.

What I want all of you to know is that we are going to bring those who killed our fellow Americans to justice.

We know the battle ahead will be long. But always remember that, no matter what obstacles stand in our way, nothing can stand in the way of the power of millions of voices calling for change.
