Practice 6　　In the course of our history, only a handful of generations have been asked to confront challenges as serious as the ones we face right now. But despite all of this—despite the enormity of the task that lies ahead—I stand here today as hopeful as ever that the United States of America will endure, that it will prevail, that the dream of our founders will live on in our time.　　It is this thread that binds us together in common effort; that runs through every memorial on this mall; that connects us to all those who struggled and sacrificed and stood here before.　　It is how this nation has overcome the greatest differences and the longest odds—because there is no obstacle that can stand in the way of millions of voices calling for change. There is no doubt that our road will be long, that our climb will be steep. But never forget that the true character of our nation is revealed not during times of comfort and ease, but by the right we do when the moment is hard. I ask you to help reveal that character once more, and together, we can carry forward as one nation, and one people, the legacy of our forefathers that we celebrate today.
