Maybe it is a little nuanced, but I think the problem is judging yourself against others (and vice versa). In other words, don’t let others’ perception of success define your vision of success.
But I think it is impossible to learn from others without comparing yourself to them (and truly inescapable living in a society). Besides, the rat race is everywhere. Especially in academia, where I’m guessing you might be heading with a focus in linguistics.
That being said, sounds like you’re in a better place mentally at 19 than I was! (I just compared myself to you) ;)
