I don't enjoy it but I know that I have got to live with [myself] if I'm not going to give it 100 per cent. The key thing is getting to the start line and knowing that I couldn't have done any more, that I didn't back off. You accept the pain, because if you didn't there would always be that element of doubt.

There are some things about being president that I still have difficulty doing. … For example, faking emotion. Because I feel it is an insult to the people I'm dealing with. For me to feign outrage, for example, feels to me like I'm not taking the American people seriously. I'm absolutely positive that I'm serving the American people better if I'm maintaining my authenticity. And that's an overused word. And these days people practice being authentic. But I'm at my best when I believe what I am saying.

The highest form that civilization can reach is a seamless web of deserved trust. Not much procedure, just totally reliable people correctly trusting one another. That's the way an operating room works at the Mayo Clinic. If a bunch of lawyers were to introduce a lot of process, the patients would all die. So never forget, when you're a lawyer, that you may be rewarded for selling this stuff, but you don't have to buy it. In your own life, what you want is a seamless web of deserved trust. And if your proposed marriage contract has forty-seven pages, my suggestion is you not enter.

I don’t think of it as research. I read for interest and enjoyment, and when I cease to enjoy it I stop. I didn’t research quantum mechanics but I was fascinated by the mystery that lies in the foundation of the observable world, of which the most familiar example is the wave/particle duality of light. I thought it was a good metaphor for human personality. The language of espionage lends itself to this duality—think of the double agent.

The inclination to pretend I read a friend’s book when maybe I didn’t completely finish.

And what happens for me is that I make a pot of beans on Sunday. And I also make some greens with chard, whatever I have available. And when I come to cook a meal or even to make myself breakfast, I may warm up some of those beans. I put a little tortilla right on the fire. I fill it up with the beans, maybe a little hot pepper, and I eat it. And that takes me exactly two minutes, three minutes, maybe. But it’s knowing how to cook. Those basic things have been taken away from us.

A lack of generosity. It can take so many forms—it doesn’t just have to do with money—so I’m always shocked when people can’t muster any at all.

My discomfort with being alone.

I believe that that is a fast-food myth to get us out there buying whatever they’re selling because I know that beans and greens are very, very affordable.

Shopping at the organic farmers market, buying whatever’s in season that looks the ripest and most vibrant, and bringing it home to cook with my friends.
