Here's the advice I give everyone about marriage — is she someone you find interesting? … You will spend more time with this person than anyone else … - Barack Obama

Some of the work confronting us will not be completed during my presidency. Some, like the elimination of nuclear weapons, may not be completed in my lifetime. But I know these challenges can be met so long as it's recognized that they will not be met by one person or one nation alone. This award is not simply about the efforts of my administration — it's about the courageous efforts of people around the world.

To those leaders around the globe who seek to sow conflict, or blame their society's ills on the West - know that your people will judge you on what you can build, not what you destroy.

That is our generation’s task -- to make these words, these rights, these values of life and liberty and the pursuit of happiness real for every American. Being true to our founding documents does not require us to agree on every contour of life. It does not mean we all define liberty in exactly the same way or follow the same precise path to happiness. Progress does not compel us to settle centuries-long debates about the role of government for all time, but it does require us to act in our time. For now decisions are upon us and we cannot afford delay. We cannot mistake absolutism for principle, or substitute spectacle for politics, or treat name-calling as reasoned debate. We must act, knowing that our work will be imperfect. We must act, knowing that today’s victories will be only partial and that it will be up to those who stand here in four years and 40 years and 400 years hence to advance the timeless spirit once conferred to us in a spare Philadelphia hall.
