Write the Essay No One Else Could Write
“It boils down to this: the essay that gets you in is the essay that no other applicant could write.
Is this a trick? The rest of this guide gives you the best strategies to accomplish this single
most important thing: write the essay no one else could write.
If someone reading your essay gets the feeling some other applicant could have written it,
then you’re in trouble.
Why is this so important? Because most essays sound like they could have been written by
anyone. Remember that most essays fail to do what they should: replace numbers (SAT/GPA) with the real you.
Put yourself in the shoes of an admissions officer. She’s got limited time and a stack of
applications. Each application is mostly numbers and other stuff that looks the same. Then she picks
up your essay. Sixty seconds later, what is her impression of you? Will she know something specifically
about you? Or will you still be indistinguishable from the hundreds of other applicants she has been
reading about?”

So you want to make this about you, not your mom or your friends. How much of your essay would you need to spend talking about their problems?
