No, not in high school.
My looks peaked in my mid-twenties, recently took a dive due to covid hair loss (short hair really doesn't suit me) and weight gain, but both are in the process of being rectified, so while I may never look my best again, I can still look pretty.
In contrast, in high school I had no style, because I was not allowed to express myself at home and barely ever had money to buy new clothes.
Academically, I peaked at university (even though I only scored in the top 15%), now my job is too specialised to allow for the vast breadth of knowledge I used to have, though I am very well-versed in what I do now.
In high school, I was top of my class, but it didn't mean much, because I was relentlessly bullied, so couldn't enjoy the satisfaction knowledge and grades could bring.
My personality and self-confidence haven't even begun to peak yet; I have only been able to build them up since my mid-30s. Suddenly, I know what I want from life beyond just my career, I don't put up with shit anymore, am more outgoing, much more comfortable in myself. It started with SSRIs and a divorce, now life is just getting better and better.
It would be sad if everything had peaked in high school - what would there be to look forward to?
