A true narcissist thinks they're better than everyone at everything. Trump is the best example of a narcissist I've ever seen. For example:
"I know more about renewables than any human being on Earth."
"I understand social media. I understand the power of Twitter. I understand the power of Facebook maybe better than almost anybody"
"Nobody knows more about debt. I'm like the king. I love debt."
"I think nobody knows more about taxes than I do, maybe in the history of the world. Nobody knows more about taxes.
"Nobody knows banking better than I do"
"I understand money better than anybody."
"I think nobody knows the system better than I do."
"I know more about contributions than anybody."
"Nobody knows politicians better than Donald Trump."
"Nobody knows more about trade than me."
"Nobody knows jobs like I do! Don’t let them sell you out!"
"Nobody in the history of this country has ever known so much about infrastructure as Donald Trump."
"There's nobody bigger or better at the military than I am."
"I know more about ISIS than the generals do. Believe me."
"There is nobody who understands the horror of nuclear more than me."
"Because nobody knows the system better than me. I know the H1B. I know the H2B. Nobody knows it better than me."
"I’m very highly educated. I know words; I have the best words."
"No one has more respect for women than me."
"I have the best temperament or certainly one of the best temperaments of anybody that’s ever run for the office of president. Ever."
"Nobody reads the Bible more than me."
"I’m the most successful person ever to run for the presidency, by far. Nobody’s ever been more successful than me."
Tired yet? Because I could go on all day with these. That's what it's like to be an actual narcissist. If that's not like you, you're probably not a narcissist.
