Observations from Tony Schwartz, ghostwriter of Art of the Deal
.....what Schwartz regards as one of Trump’s most essential characteristics: “He has no attention span.”
....He asked Trump to describe his childhood in detail. After sitting for only a few minutes in his suit and tie, Trump became impatient and irritable. He looked fidgety, Schwartz recalls, “like a kindergartner who can’t sit still in a classroom.” Even when Schwartz pressed him, Trump seemed to remember almost nothing of his youth, and made it clear that he was bored. Far more quickly than Schwartz had expected, Trump ended the meeting.
....it’s impossible to keep him focussed on any topic, other than his own self-aggrandizement, for more than a few minutes, and even then . . . ” Schwartz trailed off, shaking his head in amazement. He regards Trump’s inability to concentrate as alarming in a Presidential candidate. “If he had to be briefed on a crisis in the Situation Room, it’s impossible to imagine him paying attention over a long period of time,” he said.
....Schwartz believes that Trump’s short attention span has left him with “a stunning level of superficial knowledge and plain ignorance.” He said, “That’s why he so prefers TV as his first news source—information comes in easily digestible sound bites.” He added, “I seriously doubt that Trump has ever read a book straight through in his adult life.” During the eighteen months that he observed Trump, Schwartz said, he never saw a book on Trump’s desk, or elsewhere in his office, or in his apartment.
