Oh yes… I also spent considerable time teaching myself interesting topics. It’s a good skill to have. But I was still bored a lot of the time, and being able to do the interesting stuff in school too was a much better experience for me.
I will say one of the things that always made me laugh was that at each milestone, like finishing elementary school and starting middle school, my parents would try to tell me now it would be different, because I was at a higher level. I remember pointing out to them all the same doofuses from the previous years were moving up right along with me, and it wasn't just that I was ahead of them, but that I was faster, so this didn't seem to help. I never did understand why they thought that would work!
