I have always believed that hope is that stubborn thing inside us that insists, despite all the evidence to the contrary, that something better awaits us so long as we have the courage to keep reaching, to keep working, to keep fighting.

Hope is the bedrock of this nation. The belief that our destiny will not be written for us, but by us, by all those men and women who are not content to settle for the world as it is, who have the courage to remake the world as it should be.

I have never been more hopeful about America. And I ask you to sustain that hope. I'm not talking about blind optimism, the kind of hope that just ignores the enormity of the tasks ahead or the roadblocks that stand in our path. I'm not talking about the wishful idealism that allows us to just sit on the sidelines or shirk from a fight. I have always believed that hope is that stubborn thing inside us that insists, despite all the evidence to the contrary, that something better awaits us so long as we have the courage to keep reaching, to keep working, to keep fighting.

So tonight, I ask every American to commit to at least one year or more of higher education or career training. This can be a community college or a four-year school, vocational training or an apprenticeship. But whatever the training may be, every American will need to get more than a high school diploma.

In the white community, the path to a more perfect union means acknowledging that what ails the African-American community does not just exist in the minds of black people; that the legacy of discrimination - and current incidents of discrimination, while less overt than in the past - that these things are real and must be addressed. Not just with words, but with deeds by investing in our schools and our communities; by enforcing our civil rights laws and ensuring fairness in our criminal justice system; by providing this generation with ladders of opportunity that were unavailable for previous generations. It requires all Americans to realize that your dreams do not have to come at the expense of my dreams; that investing in the health, welfare, and education of black and brown and white children will ultimately help all of America prosper.

Today, 60 years after they rose up against oppression, we remember the East German heroes of June 17th. When the wall finally came down, it was their dreams that were fulfilled. Their strength and their passion, their enduring example remind us that for all the power of militaries, for all the authority of governments, it is citizens who choose whether to be defined by a wall, or whether to tear it down.
