"everything" is apparently not an acceptable response.
Hey, I like the beginning but advise against keeping it. "Everything" is not an acceptable response, and it is for the same reason not acceptable here. "Everything" is a typical answer from the kind of kid that does not have any ideas in mind, too preoccupied with fashion or games or other distractions.
I think you have a great theme, though. I just suggest introducing it in a different way. And I suggest this reluctantly, because you really did introduce this in a clever way. It might be my own hangup that makes me want you to not say "everything" in the essay. But you clearly are interested in science rather than psychology, literature, etc. So... let the intro to this essay give you definition, even if it is a little "reductive" in the process.
