“My friends, after years of hard work and treating people right, isn’t that what we all want to hear? Isn’t that America at our best? We don’t thrive on tearing each other apart, or separating ourselves. We know we are stronger together. We believe in equality and dignity for all. And when we fall short, we strive to do better, not to blame and scapegoat but to improve ourselves, to move toward becoming that more perfect union that our founders hoped for. This election is a chance for us to move still closer to that goal, to make sure everyone can contribute to a growing and prospering America, to say loudly and clearly in this country, no one’s worthless, no one’s ‘less than.’ We’re all of value. In the United States of America, the greatest country in the world, we believe everyone is created equal. And you know what else we believe? We all believe love trumps hate.”

2013, Commencement Address at Ohio State University (May 2013)
Context: That’s precisely what the founders left us: the power to adapt to changing times. They left us the keys to a system of self-government – the tool to do big and important things together that we could not possibly do alone. To stretch railroads and electricity and a highway system across a sprawling continent. To educate our people with a system of public schools and land grant colleges, including Ohio State. To care for the sick and the vulnerable, and provide a basic level of protection from falling into abject poverty in the wealthiest nation on Earth. To conquer fascism and disease; to visit the Moon and Mars; to gradually secure our God-given rights for all our citizens, regardless of who they are, what they look like, or who they love. 
We, the people, chose to do these things together. Because we know this country cannot accomplish great things if we pursue nothing greater than our own individual ambition. 
Still, you’ll hear voices that incessantly warn of government as nothing more than some separate, sinister entity that’s the root of all our problems, even as they do their best to gum up the works; or that tyranny always lurks just around the corner.  You should reject these voices. Because what they suggest is that our brave, creative, unique experiment in self-rule is just a sham with which we can’t be trusted.
We have never been a people who place all our faith in government to solve our problems, nor do we want it to. But we don’t think the government is the source of all our problems, either. Because we understand that this democracy is ours.  As citizens, we understand that America is not about what can be done for us. It’s about what can be done by us, together, through the hard and frustrating but absolutely necessary work of self-government. 
The founders trusted us with this awesome authority. We should trust ourselves with it, too. Because when we don’t, when we turn away and get discouraged and abdicate that authority, we grant our silent consent to someone who’ll gladly claim it.

2010s, Farewell Speech (2017)
Context: When you encounter obstacles — because I guarantee you, you will, and many of you already have — when you are struggling and you start thinking about giving up, I want you to remember something that my husband and I have talked about since we first started this journey nearly a decade ago, something that has carried us through every moment in this White House and every moment of our lives, and that is the power of hope — the belief that something better is always possible if you're willing to work for it and fight for it.
It is our fundamental belief in the power of hope that has allowed us to rise above the voices of doubt and division, of anger and fear that we have faced in our own lives and in the life of this country. Our hope that if we work hard enough and believe in ourselves, then we can be whatever we dream, regardless of the limitations that others may place on us. The hope that when people see us for who we truly are, maybe, just maybe they, too, will be inspired to rise to their best possible selves.
