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

“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.”

“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”

“Ours is not the first generation to understand the dire need for health reform. And I am not the first president to take up this cause, but I am determined to be the last.”

“America, this is our moment. This is our time. Our time to turn the page on the policies of the past. Our time to bring new energy and new ideas to the challenges we face. Our time to offer a new direction for the country we love.”

“The result is autobiographical, although whenever someone’s asked me over the course of these last three years just what the book is about, I’ve usually avoided such a description. An autobiography promises feats worthy of record, conversations with famous people, a central role in important events. There is none of that here.”

“In reaffirming the greatness of our nation, we understand that greatness is never a given. It must be earned. Our journey has never been one of shortcuts or settling for less. It has not been the path for the faint-hearted, for those who prefer leisure over work, or seek only the pleasures of riches and fame. Rather, it has been the risk-takers, the doers, the makers of things -- some celebrated, but more often men and women obscure in their labor -- who have carried us up the long, rugged path towards prosperity and freedom.”

“If they bring a knife to the fight, we bring a gun.”

“To be black was to be the beneficiary of a great inheritance, a special destiny, glorious burdens that only we were strong enough to bear. Burdens”

“A change is brought about because ordinary people do extraordinary things.”

“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.”

“Katakanlah satu hal selama kampanye dan lakukanlah hal lain begitu Anda sudah menjabat, dan Anda adalah seorang politisi yang tipikal, politisi yang bermuka dua.”

“Let me tell your something. I'm from Chicago. I don't break.”
