Two big things stick out for me.

My parents never really let me make my own choices until I was much older, around 20 years old. I would ask to take certain classes in high school or to do an extra-curricular, and there were always reasons it got shot down. I didn't have any agency over my own choices, and while they probably made a lot of good decisions for me, a few bad ones that were made for me have echoed throughout my life and they were things I actively tried to change at the time. This also meant that I never had a chance to pursue things I was interested in.

Two things that stick out:

I was offered a special internship in high school due to my knack for technology. It would have been a really basic IT/programming thing where I would skip my 4th period to drive to a local company and work until 5:30. I wasn't allowed to do this because my parents thought it would be more beneficial to stay in school for my 4th period... which ended up being guitar and a TA position, respectively, for that year. I didn't need the credits, which was part of the reason I was offered this option.

The other involved my route through college. My parents were adamant that I go to the state school my entire family has gone to and live with my grandmother. I had no interest in this, and I also felt that I was directionless in school, so eventually I managed to convince my parents that junior college would be the way to go. While there, I ended up working at a movie theater part-time, so my life for a while was work and school. The theater ended up offering me a management position, and I was still clueless about what I wanted my major to be. I wanted to take an extra year in JC while working full time, but my parents were not down for this. There was a lot of pressure for me to sign a transfer agreement and finish up college in the traditional 4 years, so I ended up taking a random major (Anthropology) and finishing out in 4 years. They were convinced that all I needed would be any degree to finish up school and get a job.

Second, my parents really sucked at punishment. I did some pretty dumb things as a kid, and my weeklong grounding would turn in to a 6 hour grounding before it eventually became "don't leave your room" which wasn't a problem because I had everything I needed in my room.
