How to get chip off my shoulder

My uncle once told me to get rid of that chip on your shoulder. I see what he means. I don't mean to act this way. There's no malice in my ways. I'm doing something wrong. I need to humble myself. What do yall suggest?

Tbh because of my work ethic, I recognize that I put in my work than everyone. It's not that I feel better than anyone, I recognize my worth. So does my superiors. I pay attention to detail more than others. I learn quickly and I retain knowledge better than most. That's not my words, that's from multiple trainers from multiple jobs that have given me the same review.

Over time this has built my ego to the point where I now have a chip on my shoulder and think that I am better than everyone. I don't think that I'm better than everyone, but my attitude? Or maybe my demeanor? I don't know what it is to be honest. But now I see it. And I want to get rid of it. How do I let go and humble myself. I know who I am but I want to portray it to everyone else. And is ruining my life. Because I don't know how to cut it off. I want to prove myself at all times. How do I humble myself?
