“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. These are the indicators of crisis, subject to data and statistics. Less measurable but no less profound is a sapping of confidence across our land — a nagging fear that America's decline is inevitable, and that the next generation must lower its sights. Today I say to you that the challenges we face are real. They are serious and they are many. They will not be met easily or in a short span of time. But know this, America — they will be met. On this day, we gather because we have chosen hope over fear, unity of purpose over conflict and discord. On this day, we come to proclaim an end to the petty grievances and false promises, the recriminations and worn out dogmas, that for far too long have strangled our politics.”

“Cynicism is a sorry kind of wisdom.”

“Change is never easy, but always possible.”

“If poverty is a disease that infects an entire community in the form of unemployment and violence, failing schools and broken homes, then we can't just treat those symptoms in isolation. We have to heal that entire community. And we have to focus on what actually works”

“Making your mark on the world is hard. If it were easy, everybody would do it. But it's not. It takes patience, it takes commitment, and it comes with plenty of failure along the way. The real test is not whether you avoid this failure, because you won't. it's whether you let it harden or shame you into inaction, or whether you learn from it; whether you choose to persevere.”

“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.”

“Di Indonesia, kekuasaan diperlihatkan secara terang-terangan, tidak pandang bulu, terbuka, selalu segar dalam ingatan.”

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

“That's what the leadership was teaching me, day by day: that the self-interest I was supposed to be looking for extended well beyond the immediacy of issues, that beneath the small talk and sketchy biographies and received opinions, people carried with them some central explanation of themselves. Stories full of terror and wonder, studded with events that still haunted or inspired them. Sacred stories. ”

“Teachers matter. So instead of bashing them, or defending the status quo, let’s offer schools a deal. Give them the resources to keep good teachers on the job, and reward the best ones. In return, grant schools flexibility: To teach with creativity and passion; to stop teaching to the test; and to replace teachers who just aren’t helping kids learn.”

“And if the high didn’t solve whatever it was that was getting you down, it could at least help you laugh at the world’s ongoing folly and see through all the hypocrisy and bullshit and cheap moralism.”

“We need to internalize this idea of excellence. Not many folks spend a lot of time trying to be excellent.”

“I’ve just concluded that for me personally it is important for me to go ahead and affirm that I think same-sex couples should be able to get married.”

“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.”

“A woman named Helen Keller fought her way through long, silent darkness. Though she could not see or hear, she taught us to look at and listen to each other. Never waiting for life to get easier, she gave others courage to face their challenges.”
