Deprivation of the ability to speak is more like an attack of impotence, or the amputation of part of the personality. To a great degree, in public and private, I “was” my voice. All the rituals and etiquette of conversation, from clearing the throat in preparation for the telling of an extremely long and taxing joke to (in younger days) trying to make my proposals more persuasive as I sank the tone by a strategic octave of shame, were innate and essential to me. I have never been able to sing, but I could once recite poetry and quote prose and was sometimes even asked to do so.

But it was quite intense to be the first Black person that my German friends had seen. Actually laid eyes, and hands, on. And there was the German language, which I had to learn, and the German kids learned British English, so my American English was frowned upon. … Maybe I write like I do because I spent those years in the cauldron of not fluently speaking the native language of my classmates. Those several years of being told that the tongue I spoke wasn’t right.

If you really want to make a difference, whether it’s in helping other people, or whether it’s in fighting for your country, or whether it’s in the political arena, or journalism, or physics, you’ve got to persevere. You’ve got to understand that there are going to be some enormous bumps in the road.

And because Fulbright was the chairman of the committee he had an automated — some sort of automated device that allowed the Pentagon to send him, every day, a list of the people who’d been killed in Vietnam from Arkansas. So I would go check it every day. Four of my high school classmates were killed, including, as I said, the son of my guy who was my Sunday school teacher for nine years. And I also knew, because I had to carry the stuff around, that not everything the government was claiming about the progress on the battlefield was true, and it’s kind of a crazy burden for a kid my age. I felt guilty I wasn’t there, and it felt futile to go. It was an awful feeling.

Scooping ice cream is tougher than it looks. … Rows and rows of rock-hard ice cream can be brutal on the wrists. … I was less interested in what the job meant for my future and more concerned about what it meant for my jump shot.

I believe in this country. I believe in the American people. I believe that people are more good than bad. I believe tragic things happen, I think there's evil in the world, but I think that at the end of the day, if we work hard, and if we're true to those things in us that feel true and feel right, that the world gets a little better each time.

You'll see I wear only gray or blue suits. … I'm trying to pare down decisions. I don't want to make decisions about what I'm eating or wearing. Because I have too many other decisions to make. … You need to focus your decision-making energy. You need to routinize yourself. You can't be going through the day distracted by trivia.

One of the things that Michelle and I are proud of is that we came through the White House with our souls intact. Everybody has heard: Power corrupts. I do think if you are placed in such an artificial situation, and your office has great importance, there is a tendency for people to want to please you. To not be as honest with you. We fought against that.

Part of what separates us from the other creatures on earth is that we make up stories. We are storytellers. And we can tell bad stories and we can tell good stories. We can tell stories that lead to division and hate and war. Or we can tell stories that lead to cooperation and peace and progress.

Sometimes I wrote off my own failings as just another example of the world trying to keep a black man down. I had a tendency sometimes to make excuses for me not doing the right thing.
