anything at all is more than appreciated
"Anything at all" is not sufficient.
Below are some general comments. If you'd like me to edit this paper, I'll be glad to do so IF it isn't due tomorrow and IF you take my suggestions to heart:
1. Reread the prompt. You have only implicitly expressed your desire to be a PA. Too much---far too much, really---of this essay is a list of things you've done. No effective essay is controlled by facts or events. In fact, every paragraph except the conclusion begins with a fact.
2. Your sentence variety is far better than average; from a mechanical standpoint you're an excellent writer. Your essay does NOT need much proofreading. (Proofreading done incorrectly will
harm this paper.) Rather, it requires the most subtle of editorial changes.
3. Part of the "subtle editing" to which I refer above involves the removal of words that serve no purpose. Without giving away all my professional secrets, here are a few of these words:
---this, that (the pronoun form, not the conjunction)
---the verbs "to have" and "to make" (Yes, I know Emerson uses "make." Keep that one.)
---it
---positive/negative
---thing
Not ALL of these need to removed in EVERY instance in EVERY piece of writing...but they pretty much do need to disappear from yours, especially given that you have a wordiness problem.
I also see a couple of misplaced modifiers.
Anyhoo...the quality of your writing alone distinguishes this from two-thirds of all admissions essays. Unlike most of the admissions essays I see, this one will NOT hurt your chances, even when I take into account the problems noted above.
