What it's like to be president

“You have to exercise,” he said, for instance. “Or at some point you’ll just break down.” You also need to remove from your life the day-to-day problems that absorb most people for meaningful parts of their day. “You’ll see I wear only gray or blue suits,” he said. “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.” He mentioned research that shows the simple act of making decisions degrades one’s ability to make further decisions. It’s why shopping is so exhausting. “You need to focus your decision-making energy. You need to routinize yourself. You can’t be going through the day distracted by trivia.” The self-discipline he believes is required to do the job well comes at a high price. “You can’t wander around,” he said. “It’s much harder to be surprised. You don’t have those moments of serendipity. You don’t bump into a friend in a restaurant you haven’t seen in years. The loss of anonymity and the loss of surprise is an unnatural state. You adapt to it, but you don’t get used to it—at least I don’t...” 

Many if not most of his decisions are thrust upon the president, out of the blue, by events beyond his control: oil spills, financial panics, pandemics, earthquakes, fires, coups, invasions, underwear bombers, movie-theater shooters, and on and on and on. They don’t order themselves neatly for his consideration but come in waves, jumbled on top of each other. “Nothing comes to my desk that is perfectly solvable,” Obama said at one point. “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.” On top of all of this, after you have made your decision, you need to feign total certainty about it. People being led do not want to think probabilistically... 

“Obama structures meetings so that they’re not debates,” says one participant. “They’re mini-speeches. He likes to make decisions by having his mind occupying the various positions. He likes to imagine holding the view”... His desire to hear the case raises the obvious question: Why didn’t he just make it himself? “It’s the Heisenberg principle,” he says. “Me asking the question changes the answer. And it also protects my decision-­making.” But it’s more than that. His desire to hear out junior people is a warm personality trait as much as a cool tactic, of a piece with his desire to play golf with White House cooks rather than with C.E.O.’s and basketball with people who treat him as just another player on the court; to stay home and read a book rather than go to a Washington cocktail party; and to seek out, in any crowd, not the beautiful people but the old people. The man has his stat­us needs, but they are unusual. And he has a tendency, an unthinking first step, to subvert established stat­us structures. After all, he became president."
