“We say we value the legacy we leave the next generation and then saddle that generation with mountains of debt. We say we believe in equal opportunity but then stand idle while millions of American children languish in poverty. We insist that we value family, but then structure our economy and organize our lives so as to ensure that our families get less and less of our time.”

“But by the end of two years, most have either changed careers or moved to suburban schools - a consequence of low pay, a lack of support from the educational bureaucracy, and a pervasive feeling of isolation.”

“You can’t let your failures define you. You have to let your failures teach you.”

“In the end, that's what this election is about. Do we participate in a politics of cynicism or a politics of hope?”

“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.”

“If the people cannot trust their government to do the job for which it exists – to protect them and to promote their common welfare – all else is lost.”

“The most important thing you need to do [in this job] is to have big chunks of time during the day when all you’re doing is thinking.”

“At some fundamental level, religion does not allow for compromise. It insists on the impossible. If God has spoken, then followers are expected to live up to God's edicts, regardless of the consequences. To base one's life on such uncompromising commitments may be sublime; to base our policy making on such commitments would be a dangerous thing.”

“We are the change we have been waiting for.”

“It's only when you hitch your wagon to something larger than yourself that you realize your true potential.”

“When you get rid of the estate tax,” he (Warren Buffet) said, “you’re basically handing over command of the country’s resources to people who didn’t earn it. It’s like choosing the 2020 Olympic team by picking the children of all the winners at the 2000 Games.”

“We will restore science to its rightful place and wield technology's wonders to raise health care's quality and lower its cost.”

“Semakin aku mengenal sistem, semakin aku yakin bahwa reformasi pendidikan adalah satu-satunya solusi bagi remaja bermasalah di luar sana. Tanpa keluarga yang stabil, tanpa prospek mendapatkan pekerjaan bergengsi yang akan membantu keuangan keluarga, pendidikan adalah harapan terbesar mereka.”

“I wish the country had fewer lawyers and more engineers.”

“There is no excuse for not trying.”
