Some of the most distinguished mental health professionals in this country have come to the same conclusion. Trump's numerous romantic escapades and the growing number of sexual harassment lawsuits and his three marriages in which he "traded up" for younger, more beautiful women along with his ever-shifting political alliances prove his main focus is severe self-interest i.e., unbridled or extreme, present hedonist.

"'Donald Trump is the most dangerous man in the world,' writes another famous contributor to the book, Philip Zimbardo, professor emeritus at Stanford University and a scholar-author best known for his landmark prison study.
"The call to action for Zimbardo came when he recognized in Trump the pathological behavior he has defined as 'extreme present hedonism.'
"These are people who live for the moment, he told me, 'mostly children, but some adult hedonists, too. They make decisions on the spur of the moment, never thinking about the consequences.'
"Easily bored, they constantly seek novelty and are vulnerable to addiction.
"This extreme present hedonism is apparent in Trump, 'because he will say whatever it takes to pump up his ego and to assuage his inherent low self-esteem, without any thought for the potentially devastating future outcomes from his off-the-cuff remarks or even major decisions,' according to the scholar psychologist."
