I learned at all early age the only thing appearing like the smartest guy in the room was good for was paining a target on your back. I also learned how to emulate empathy, it's not perfect, but it makes up for the natural broken/missing wiring in my head.

Also early in my career I talked my way out of several jobs, You might have the best ideas in the world, but if powers that be don't want to hear them, don't belabor the matter, give your suggestions and move on.

I started out too in customer support, 20 years later I'm making an engineers salary, with an engineering title, which isn't too bad for a drop out.

The best advice on jobs I have, take a bad shitty job that's good for your resume, work there till you have the book experience to work someplace else, rinse and repeat,
