People who make $75k or more how did you pull it off? It seems impossible to reach that salary

So I’m 32 years old making just under 50k in inbound sales at a call center. And yes I’ve been trying to leave this job for the past two years. I have a bachelors degree in business but can not break through. I’ve redone my resume numerous times and still struggling. Im trying my hardest to avoid going back to school for more debt. I do have a little tech background being a former computer science student but couldn’t afford I to finish the program. A lot of people on Reddit clear that salary easily, how in the hell were you able to do it? Also I’m on linked in all day everyday messaging recruiters and submitting over 500+ resume, still nothing.

Edit - wow I did not expect this post to blow up the way it did, thank you for all the responses, I’m doing my best to read them all but there is a lot.
