“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.”

“Life doesn't count for much unless you're willing to do your small part to leave our children – all of our children – a better world. Even if it's difficult. Even if the work seems great. Even if we don't get very far in our lifetime.”

ilainya meragukan namun tidak mau menggunakan uang itu untuk melindungi pabrik-pabrik kimia yang sangat rapuh di pusat-pusat urban yang utama, menjadi semakin sulit bagi kita untuk meminta negara-negara lain menjaga pabrik-pabrik tenaga nuklir mereka.”

“For as much as government can do and must do, it is ultimately the faith and determination of the American people upon which this nation relies. So let us mark this day with remebrance, of who we are and how far we have traveled.”

“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.”

“It was the call of workers who organized; women who reached for the ballot; a President who chose the moon as our new frontier; and a King who took us to the mountain top and pointed the way to the Promised Land. Yes we can!”

“Negara yang tidak bisa mengendalikan sumber energinya, tidak bisa mengendalikan masa depannya.”

“Hope is not blind optimism. It's not ignoring the enormity of the task ahead or the roadblocks that stand in our path. It's not sitting on the sidelines or shirking from a fight. Hope is that thing inside us that insists, despite all evidence to the contrary, that something better awaits us if we have the courage to reach for it, and to work for it, and to fight for it. Hope is the belief that destiny will not be written for us, but by us, by the men and women who are not content to settle for the world as it is, who have the courage to remake the world as it should be.”

“Someone once said that every man is trying to live up to his father's expectations or make up for their father's mistakes....”

“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.”

“Maybe the critics are right. Maybe there's no escaping our great political divide, an endless clash of armies, and any attempts to alter the rules of engagement are futile. Or maybe the trivialization of politics has reached a point of no return, so that most people see it as just one more diversion, a sport, with politicians our paunch-bellied gladiators and those who bother to pay attention just fans on the sidelines: We paint our faces red or blue and cheer our side and boo their side, and if it takes a late hit or cheap shot to beat the other team, so be it, for winning is all that matters. But I don't think so. They are out there, I think to myself, those ordinary citizens who have grown up in the midst of all the political and cultural battles, but who have found a way-in their own lives, at least- to make peace with their neighbors, and themselves. ...I imagine they are waiting for a politics with the maturity to balance idealism and realism, to distinguish between what can and cannot be compromised, to admit the possibility that the other side might sometimes have a point. They don't always understand the arguments between right and left, conservative and liberal, but they recognize the difference between dogma and common sense, responsibility and irresponsibility, between those things that last and those that are fleeting. They are out there, waiting for Republicans and Democrats to catch up with them.”

“You might be locked in a world not of your own making, her eyes said, but you still have a claim on how it is shaped. You still have responsibilities.”

“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.”

“What Washington Needs is Adult Supervision.”

“To the furniture worker's child in North Carolina who wants to become a doctor or a scientist, an engineer or an entrepreneur, a diplomat or even a president -- that's the future we hope for. That's the vision we share. That's where we need to go -- forward”
