“Focusing your life solely on making a buck shows a certain poverty of ambition. It asks too little of yourself. Because it's only when you hitch your wagon to something larger than yourself that you realize your true potential.”

“For us, they packed up their few worldly possessions and traveled across oceans in search of a new life.”

“And that brings me to one last point. I've got a simple message for all the dedicated and patriotic federal workers who have either worked without pay, or who have been forced off the job without pay for these last few weeks. Including most of my own staff. Thank you. Thanks for your service. Welcome back. What you do is important. It matters. You defend our country overseas, you deliver benefits to our troops who earned them when they come home, you guard our borders, you protect our civil rights, you help businesses grow and gain footholds in overseas markets. You protect the air we breathe, and the water our children drink, and you push the boundaries of science and space, and you guide hundreds of thousands of people each day through the glories of this country. Thank you. What you do is important, and don't let anybody else tell you different.”

“At the moment that we persuade a child, any child, to cross that threshold, that magic threshold into a library, we change their lives forever, for the better.”

“For in the end laws are just words on a page - words that are sometimes malleable, opaque, as dependent on context and trust as they are in a story or poem or promise to someone, words whose meanings are subject to erosion, sometimes collapsing in the blink of an eye.”

“I don’t think I really like myself. And I blame the Old Man for this.”

“Conservatives may be right when they argue that the government should not try to determine executive pay packages.

“No, no. I have been practicing...I bowled a 129. It's like -- it was like Special Olympics, or something." --making an off-hand joke during an appearance on "The Tonight Show", March 19, 2009”

“That we are in the midst of crisis is now well understood. Our nation is at war, against a far-reaching network of violence and hatred. Our economy is badly weakened, a consequence of greed and irresponsibility on the part of some, but also our collective failure to make hard choices and prepare the nation for a new age. Homes have been lost; jobs shed; businesses shuttered. Our health care is too costly; our schools fail too many; and each day brings further evidence that the ways we use energy strengthen our adversaries and threaten our planet.”

“We remain a young nation, but in the words of Scripture, the time has come to set aside childish things. The time has come to reaffirm our enduring spirit; to choose our better history; to carry forward that precious gift, that noble idea, passed on from generation to generation: the God-given promise that all are equal, all are free, and all deserve a chance to pursue their full measure of happiness.”

“I only know what I have seen. What I have not seen doesn't make my heart heavy.”

“My heart is filled with love for this country.”

“This world is like a big classroom, and USA is the teacher, while other countries are the students, as one student tries to mess with the teacher, or does something really bad. The teacher shall teach him a nice lesson. Use your brain before you try to mess with the odds.”

“People with disabilities deserve the chance to build a life for themselves in the communities where they choose to live.”

“This election is about the past vs. the future. It's about whether we settle for the same divisions and distractions and drama that passes for politics today or whether we reach for a politics of common sense and innovation, a politics of shared sacrifice and shared prosperity. There are those who will continue to tell us that we can't do this, that we can't have what we're looking for, that we can't have what we want, that we're peddling false hopes. But here is what I know. I know that when people say we can't overcome all the big money and influence in Washington, I think of that elderly woman who sent me a contribution the other day, an envelope that had a money order for $3.01 along with a verse of scripture tucked inside the envelope. So don't tell us change isn't possible. That woman knows change is possible. When I hear the cynical talk that blacks and whites and Latinos can't join together and work together, I'm reminded of the Latino brothers and sisters I organized with and stood with and fought with side by side for jobs and justice on the streets of Chicago. So don't tell us change can't happen. When I hear that we'll never overcome the racial divide in our politics, I think about that Republican woman who used to work for Strom Thurmond, who is now devoted to educating inner city-children and who went out into the streets of South Carolina and knocked on doors for this campaign. Don't tell me we can't change. Yes, we can. Yes, we can change. Yes, we can. Yes, we can heal this nation. Yes, we can seize our future. And as we leave this great state with a new wind at our backs and we take this journey across this great country, a country we love, with the message we carry from the plains of Iowa to the hills of New Hampshire, from the Nevada desert to the South Carolina coast, the same message we had when we were up and when we were down, that out of many, we are one; that while we breathe, we will hope. And where we are met with cynicism and doubt and fear and those who tell us that we can't, we will respond with that timeless creed that sums up the spirit of the American people in three simple words -- yes, we can.”
