My youngest sis is ENTJ and I watched her grow up. She is the most confident, arrogant person I have ever met. She's more than a decade younger than me, but we are extremely close - actually probably my best friend, if I had to quantify it. Every time she starts a job, within 2 weeks she'll start complaining about their inefficiency. Within a month, she'll start saying how much better she is than everyone else. And she's right - she
is just better than anyone else, and it's painfully obvious to anyone around her. She has been eternally loved by all of her bosses because she puts on a good game face of the intelligent, competent, sweet girl and she will never leave for the day unless everything is completed.
When she was 16, I hired her as a production manager for a film that I was working on. I have never met anyone before or since who could do the job with the precision that she did. She researched the entire film industry and her job title, read the screenplay, spoke to the director (who thought she was a 30yo woman) and showed up on day one with color coded charts and schedules, personalized for each member of each crew. She is ridiculous. If we were in a war, she would be the general and I would be her adviser.
As a kid, she was extremely competitive and jealous for no reason. If she heard me playing a song on the piano, she would (as a very young child) wake up in the middle of the night and sneak down to practice (as if we wouldn't hear her!) and play it for me with precision the next day with a smug look on her face. One of my other sister's is a visual artist, and my ENTJ was so jealous of her talent and would spend countless hours painstakingly copying everything she ever drew. Now, she is an amazing artist herself, but she has the same exact style as our sister. Even the same handwriting.
Even as a toddler, she was competitive. She decided one day that she wants to be like the big girls and she literally potty trained herself. It took her about 2 days and then she moved on to the next task. I think one of her first complete sentences, one that she repeated often as a kid, was: who do you think is better?
Her sense of humor is sharp and witty but some people think she's a huge bitch because of it. But I get her and understand her and I know that she is not a bitch. She's just got the same sense of communication as me, but always takes that one step that I don't take - that one step
too far. And she uses insulting words. When I point out that she is being an asshole, we break into hysterical laughter because she doesn't see herself. But people who don't know her, don't realize that she would just laugh and apologize about it if you told her. Instead, they just get scared.
She totally geeks out to video games and anime conventions, making the biggest and best costumes - one for each day of the convention. But she's an undercover nerd, you would never know because she looks and acts so damn cool. Men love her but women hate her. And she always has some broken down sap of a boyfriend in tow to do her bidding.
I hate sharing a platter with her at a restaurant. She even eats competitively, eating quickly and watching you like a hawk to make sure you don't get more than her.
She always wants to be the best, but she has so many interests that she sometimes gives up too soon when she realizes how much effort she has to put in. She's lovable and hilariously funny, but my whole family is terrified of her. I understand both points of view though, because she takes everything you say quite literally. If you say "let's try to get together on Saturday" - she takes that as a fixed meeting and will crucify you if you don't show up. And she can hold a grudge for years, waiting to punish you.
