I went to the opera practically every night. I went to something practically every night, just learning and seeing and absorbing, and what I noticed is that there were singers that were only sort of slightly older than I whose voices sounded as though they were many decades older than that, and didn’t sound pretty, and I needed to understand what was happening. I mean there were singers that were 28 or 30 years old or something, and I would speak to them afterwards to say, “Was your voice tired tonight? Tell me what’s happening,” because I didn’t understand it. Their voices should have sounded fresh and blooming and wonderful, but instead they sounded different, and it was because they were singing a different opera every night, and singing whatever was offered, and I didn’t understand and needed to understand — because no one was telling me these things — why they just didn’t say no. Why didn’t they just say, “Oh no, I don’t think I should.”

I already knew this, because I had been studying classical ballet for a long time. But a lot of people insisted on a wall between modern dance and ballet, that the two disciplines were totally separate, and if you did one, you couldn’t do the other. I’m beginning to think that walls are very unhealthy things.

I never wanted to have to choose between tennis and a family. I don't think it's fair. If I were a guy, I wouldn't be writing this because I'd be out there playing and winning while my wife was doing the physical labor of expanding our family.

Unfortunately. And it’s mostly a made-up story. It was incredible to see how it was created here. All over the news: Muslim rage or whatever. The rioting was not about being Muslim. These people have not been able to integrate. So if they have a crisis of identity, it’s forced upon them. If, after three generations of living in France, Arabs are still called Arabs and not French, then of course they will be angry. People ask why the Arabs don’t consider themselves French. Well, it’s because the French don’t consider them French. Then you had the Ministry of the Interior talking about cleaning the scum off the street. That doesn’t justify the violence—they don’t have the right to burn cities—but it explains what happened.

Security. People naturally resist change in our personal lives. … Malia, actually, was the one who brought it up because she says, 'You know, one of the things that happens is sometimes transitions are hard, and I really enjoy my life, and I like how things are going.' And I said, 'Get in the habit of being able to embrace change, and what's new. Because you don't want to live your life where, you are held back because you've gotten too comfortable, and you are afraid of what might be out there around the corner.'

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.

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.

When I am on my deathbed, and I am thinking back on my life, I am absolutely certain that the thing I will be thinking about is holding my daughters' hands and taking them to the park. It will not be some speech I gave or some legislation that I passed. I am positive about that. And so if you keep that in mind, then you have to invest accordingly.

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.
