“I'm concerned about a better world. I'm concerned about justice; I'm concerned about brotherhood; I'm concerned about truth. And when one is concerned about that, he can never advocate violence. For through violence you may murder a murderer, but you can't murder murder. Through violence you may murder a liar, but you can't establish truth. Through violence you may murder a hater, but you can't murder hate through violence. Darkness cannot put out darkness; only light can do that.”

“For we all often stumble and fall and offend in many things. And if anyone does not offend in speech [never says the wrong things], he is a fully developed character and a perfect man, able to control his whole body and to curb his entire nature. JAMES 3:2 According to this Scripture, the one thing proving our level of spiritual maturity isn’t how religious we are—whether we can quote Scripture, or the good works we do—it is the words from our mouths.”

“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.”

“Know the reasons you and your listener want to communicate and build a bridge between those reasons.”

“Tanda kecerdasan sejati bukanlah pengetahuan tapi imajinasi.”

“By concentrating single-mindedly on your most important task, you can reduce the time required to complete it by 50 percent or more. It has been estimated that the tendency to start and stop a task—to pick it up, put it down, and come back to it—can increase the time necessary to complete the task by as much as 500 percent. Each time you return to the task, you have to familiarize yourself with where you were when you stopped and what you still have to do. You have to overcome inertia and get yourself going again. You have to develop momentum and get into a productive work rhythm. But when you prepare thoroughly and then begin, refusing to stop or turn aside until the job is done, you develop energy, enthusiasm, and motivation. You get better and better and more productive. You work faster and more effectively.”

“I was a young man who attempted to make up for his ignorance with militancy.”

“When you get yourself under complete control, you can be your own boss.”

“What we work out in our journals we don’t take out on family and friends.”

“I say to you today, my friends, that in spite of the difficulties and frustrations of the moment, I still have a dream. It is a dream deeply rooted in the American dream. I have a dream that one day this nation will rise up and live out the true meaning of its creed: "We hold these truths to be self-evident: that all men are created equal." I have a dream that one day on the red hills of Georgia the sons of former slaves and the sons of former slaveowners will be able to sit down together at a table of brotherhood. I have a dream that one day even the state of Mississippi, a desert state, sweltering with the heat of injustice and oppression, will be transformed into an oasis of freedom and justice. I have a dream that my four children will one day live in a nation where they will not be judged by the color of their skin but by the content of their character.”

“Relational skills are the most important abilities in leadership.”

“Los grandes líderes buscan y encuentran a líderes en potencia, y los transforman en buenos líderes.”

“I am a deeply religious nonbeliever. This is a somewhat new kind of religion.”

“first things that a hurting person needs to do is break the habit of using other people as a narcotic to numb the dull aching of an inner void.”

“God’s holiness demands that sin be punished—but God’s love has provided the way of redemption through Christ.”
