I am not on the spectrum (I follow the community because I have 2 kids on the spectrum). I did, however, go to high school and also thought I was smarter than everyone else. I was probably smarter than some people. But as I've grown up, my perspective has shifted: (1) smarts are genetic, like being pretty, and both are like winning the genetic lottery. In contrast, people who work hard have earned it. (2) Being academically gifted does not always translate into success later in life. EQ, hard work and luck also play into it. Anywho, I thought I would pass that along because I'm not so sure you are a narcissist, but maybe just haven't had as much experience. Best of luck to you!
