@coolweather how so?
Your voice is no longer genuine. Some people may just change your essay a little bit then submit.
No one actually changed my essay. They just gave me a few pointers on things that could be improved (i.e grammar, flow, etc). @coolweather
OP someone might just change your essay a little and submit as their own. in case they apply to Stanford and the admissions read his essay before yours he might get accepted and you on the other hand might be in trouble.
So don’t just send everyone your essay. You’ve gotten a few opinions(Including mine 
) and I think thats good enough. Do you feel you’ve conveyed what you wanted to? If so good. Or else just try refining your voice more.
Just satisfy yourself with the essay and thats the best form of evaluation that you can get.
@Nikshep, you are right. Thanks for your feedback by the way. Hopefully no one will do that. 
^^ same!!
