I wrote The Art of the Deal with Trump. His self-sabotage is rooted in his past.

Washinton Post:

To survive, I concluded from our conversations, Trump felt compelled to go to war with the world. It was a binary, zero-sum choice for him: You either dominated or you submitted. You either created and exploited fear or you succumbed to it — as he thought his older brother had. This narrow, defensive worldview took hold at a very early age, and it never evolved. “When I look at myself today and I look at myself in the first grade,” he told a recent biographer, “I’m basically the same.” His development essentially ended in early childhood.

A key part of that story is that facts are whatever Trump deems them to be on any given day. When he is challenged, he instinctively doubles down — even when what he has just said is demonstrably false. I saw that countless times, whether it was as trivial as exaggerating the number of floors at Trump Tower or as consequential as telling me that his casinos were performing well when they were actually going bankrupt. In the same way, Trump sees no contradiction at all in changing his story about why he fired Comey and then undermining the explanatory statements of his aides, or in any other lie he tells. His aim is never accuracy; it’s domination.

Trump derives his sense of significance from conquests and accomplishments. “Can you believe it, Tony?” he would often begin late-night conversations with me, and then go on to describe some new example of his brilliance. But the reassurance he got from even his biggest achievements was always ephemeral and unreliable — and that appears to include being elected president. On the face of it, Trump has more opportunities now to feel significant and accomplished than almost any human being on the planet. But that’s like saying that a heroin addict has his problem licked once he has free and continuous access to the drug. Trump also now has a far bigger and more public stage on which to fail and to feel unworthy.

In the hundreds of Trump’s phone calls I listened in on with his consent, and the dozens of meetings I attended with him, I can never remember anyone disagreeing with him about anything. The same climate of fear and paranoia appears to have taken root in his White House.

1. "I can never remember anyone disagreeing with him about anything"

That is how Donald Trump governs.
