His mornings, he said, are spent as they were in Trump Tower. He rises before 6 a.m., watches television tuned to a cable channel first in the residence, and later in a small dining room in the West Wing, and looks through the morning newspapers: The New York Times, The New York Post and now The Washington Post.

But his meetings now begin at 9 a.m., earlier than they used to, which significantly curtails his television time. Still, Mr. Trump, who does not read books, is able to end his evenings with plenty of television.

In between, Mr. Trump signs executive orders in the Oval Office and has meetings in the West Wing.

“They have a lot of board rooms,” he said of the White House, an apparent reference to the Cabinet Room and the Roosevelt Room.

The White House is the only property that Mr. Trump has slept in that is more famous than one of his own, and he seems in awe. Although he made his name building extravagant, gilded properties, the new president has marveled to aides about the splendor of the White House and the lengths he must walk to retrieve something from a far-flung room.

His preference during the day is to work in the Oval Office. And to stare at it, still. So do his staff members and relatives. “I’ve had people come in; they walk in here and they just want to stare for a long period of time,” Mr. Trump said.
