I don't know if this is related, but growing up there were certain values instilled in me that went something like "don't toot your own horn," "it's better to be seen and not heard," "keep your head down," etc. The main gist being that I should just do my job quietly, competently, and stay out of the way.

In practice, this resulted in me being effectively invisible to management, even when I was out-performing everyone else on the team. The guys who were loud and boisterous and constantly cawing about their achievements got all the raises and promotions, even though I was consistently doing more and better work. This came to a head when someone with far less seniority was promoted over me. I brought it up with my boss who said something like "I don't even know what you do all day. I never hear from you." The guy who was promoted would literally spend twice as much time boasting about what he was doing that actually doing it. I was objectively more productive, as in, there were metrics showing my productivity was significantly higher, but since I wasn't talking about what I was doing, I was unseen.
