“It [is] that courage that Africa most desperately needs.”

“This victory alone is not the change we seek; it is only the chance for us to make that change.”

“If my father hadn’t exactly disappointed me, he remained something unknown, something volatile and vaguely threatening

“the truth of that proposition and act on it, then we might not solve every problem, but we can get something meaningful done. It was a pretty convincing”

“As president, I believe that robotics can inspire young people to pursue science and engineering. And I also want to keep an eye on those robots in case they try anything.”

“Cynicism is a choice, and hope is a better choice.”

“He's basically a good man. But he doesn't know me. Any more than he knew that girl that looked after your mother. He can't know me, not the way I know him. Maybe some of these Hawaiians can, or the Indians on the reservation. They've seen their fathers humiliated. Their mothers desecrated. But your grandfather will never know what that feels like.”

“We talk to these folks because they potentially have the best answers, so I know whose ass to kick.”

“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.”

“This country of ours has more wealth than any nation, but that's not what makes us rich. We have the most powerful military on Earth, but that's not what makes us strong. Our universities and our culture are the envy of the world, but that's not what keeps the world coming to our shores.  It is that American spirit - that American promise - that pushes us forward even when the path is uncertain; that binds us together in spite of our differences; that makes us fix our eye not on what is seen, but what is unseen, that better place around the bend”

“When people at dinner parties ask me how I can possibly operate in the current political environment, with all the negative campaigning and personal attacks, I may mention Nelson Mandela, Aleksandr Solzhenitsyn, or some guy in a Chinese or Egyptian prison somewhere. In truth, being called names is not such a bad deal.”

“There will be setbacks and false starts. There are many who won't agree with every decision or policy I make as president. And we know the government can't solve every problem. But I will always be honest with you about the challenges we face. I will listen to you, especially when we disagree. And, above all, I will ask you to join in the work of remaking this nation, the only way it's been done in America for 221 years -- block by block, brick by brick, calloused hand by calloused hand.”

“We did not come here to fear the future. We came here to shape it.”

“And I would shrug and play the question off, unable to confess that I could no longer distinguish between faith and mere folly, between faith and simple endurance; that while I believed in the sincerity I heard in their voices, I remained a reluctant skeptic, doubtful of my own motives, wary of expedient conversion, having too many quarrels with God to accept a salvation too easily won.”

“Where you are right now doesn't have to determine where you'll end up”
