1) Been accelerated after I had formed a pretty tight friend group with my same-aged peers (jumped 2 years of math in 7th-8th grade)
2) Been born in a time where the internet was modern enough that we could all hang out and game online
I entered University at 16 (the PSEO program in MN that pays for tuition and books your junior and senior year of high school), but was able to keep in touch with my high-school friend group with multiplayer video games.
Even today, a decade later, I'm still able to keep in touch with them almost daily even though I'm living in Taiwan (started the digital nomad thing soon after graduating University at 20).
Academically I did _really_ well in a large University environment with a lot more autonomy, freedom, and responsibility (it's insane to me that we have 18 year olds still needing to ask permission to go to the bathroom during class).
Socially, I'll admit that I struggled to make any college-aged friends, but I think that was more due to still living at home than anything else. Instead of being able to take people up on offers to hang out at night, I had to make the last bus out of Minneapolis to my small town by 6:30pm.
