Honestly it's too late to drastically change the content of your essay, but we can fix a few issues with grammar.
By working cohesively alongside teachers, I assist class learning by interacting with the students and promoting growth.
Delete cohesively - it's just not a word that works well in this situation. You can either say "promoting growth" or "promoting a growth in confidence"
Some are heroic figures, emanating admirable well-known success.
Ululating is a fast-paced, war-like cry - emanating is a better word here.
You have written a good essay, but I fear it's just not related enough to the prompt. You can make this essay so much better by simply including an introduction similar to this:
"I did not believe I was a role model. I had always looked up to others, constantly deferring leadership. Until I interacted with other students in a school program, I was unable to realize my potential as a brilliant leader. The experience with the students enlightened me - through them, I was able to better myself while bettering someone else."
It doesn't have to be exactly like that, but it should be similar to it. By saying something like this you clearly answer the prompt - you show how an event changed your mind about something. I'm not sure if acquiring a personality trait counts as changing your mind, but what can you do about it now?
Ignore anything behind this line if you are crunched for time!!!!!!!!!!!!If you had more time I would try an essay that reflected a structure similar to what I am going to make up on the spot right now:
In 2010, an issue regarding collective bargaining divided the state of Wisconsin. My thoughts on this event defined the set of first political beliefs that I possessed. However, after realizing the rashness of my decision - my inability to analyze ALL issues rather than just one, I have converted my political beliefs. Watching youtube videos over the summer about paul ryan led me to this change. I always thought my beliefs were in line with the Democrats simply because of one issue, but by opening my mind up to other ideas, I was able to realize that, overall, I agree with them more than I do the Democrats.That's just a way I think the prompt should be approached. If you see it again, take an approach like this.
Define something that matters to you: In my case - politics
Define the initial stance that you took: In my case - siding with democrats
Define the stance you took after an event - In my case - becoming a libertarian
Provide examples of what prompted this change - In my case - watching videos of the other side
What was wrong with the way you made the decision the first time? - in my case -jumping to conclusions too fast.
You'll just have to work with the essay you have - It's good enough that the admissions department may not care that the prompt was left unaddressed - it does fill us in on who you are as a person.
Good luck, and pardon my overload of information.
