What am I doing wrong?

I’m 27. I’ve been working since I was 16. I’ve had numerous jobs, retail / healthcare / cosmetology/ food service / financial etc.

I’ve come to notice something: every job I’ve had I end up training new hires, who then end up being promoted to my superiors. Nobody that was in charge of me ever seemed to come up with a legitimate reason as to why I couldn’t be promoted, or have raises etc. So each time, I left and tried again someplace else. What am I doing wrong? The common denominator is obviously me as I have had 10+ jobs in my life and can recall this same scenario occurring in each one.
