Living in a campervan for a week with Timmy Mallett for a children’s TV show about 40 years ago.

Washing dishes when I was a student.

Working in a warehouse, packing frozen meat. It was a nightmare: I hate the cold and it was very tough.

I had a cafeteria job, serving food, and some people were really nasty. There was a stack of nice, cool plates, and a stack of hotter plates that had just come out of the kitchen. So, if a person was an arsehole, I’d hand them a hot plate with a smile and watch them deal with it.

I deeply regret not having learned a musical instrument. And I regret not having focused more on Spanish when I was studying it in school. I would love to be able to speak Spanish fluently and play an instrument.

Nothing comes to my desk that is perfectly solvable. … Otherwise, someone else would have solved it. So you wind up dealing with probabilities. Any given decision you make you'll wind up with a 30 to 40 percent chance that it isn't going to work. You have to own that and feel comfortable with the way you made the decision. You can't be paralyzed by the fact that it might not work out.

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.'

What makes me proudest about them is that they also don't get cynical about it. They have not assumed because their side didn't win, or because some of the values that they care about don't seem as if they were vindicated, that automatically America has somehow rejected them or rejected their values.

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.

And finally, change requires more than just speaking out -- it requires listening, as well. In particular, it requires listening to those with whom you disagree, and being prepared to compromise. When I was a state senator, I helped pass Illinois's first racial profiling law, and one of the first laws in the nation requiring the videotaping of confessions in capital cases. And we were successful because, early on, I engaged law enforcement.
