Hey, you are totally allowed! You and I probably value things differently! I'm a parent now, my values have shifted over time, and I got really burned out trying to improve things over there. I didn't like that once I became a manager I was pressured to identify and remove (rather than train/help) my people who weren't top tier. Those could have been things local to my org. If you are happy, be proud of what you are doing.
Like I said, I think it was a really valuable 6 years. I'm glad I was there, I learned a ton, met awesome engineers.
