Writing a flashback essay. Help ASAP

<p>Hi! I have written most of my essays, and I loved them a lot until I saw a post by Bryan G Nance from MIT( you can see it [url=<a href="http://mitadmissions.org/blogs/entry/ive_got_99_problems_admissions%5Dhere%5B/url"&gt;http://mitadmissions.org/blogs/entry/ive_got_99_problems_admissions]here[/url&lt;/a&gt;]. 2nd point.)
He says never write a flashback essay. I'm worried as I have written my Common App essay and an MIT essay as flashbacks.
Here is it's organization:
[An event in 12th grade that led me to look back in my life].. Description of that past event and what I learnt from it..[ back to that 12th grade event].
Essay ends.
Is this a flashback essay? What on the earth is wrong with it? Is what Nance said true for MIT or any other college too? Reply urgently because if it's the case, I better get crackin' on my new essays!
PS: i made the same post on College Essays forum too, but I think I can get an MIT-specific advice on this forum.
PPS: Help Me ASAP!! Chris/Mollie/Piper/Lydia/Mikalye/ANYONE who can help me.
THX :)</p>

<p>eh if it’s a good essay then it works. if it’s not a good essay if it doesn’t. i’m technique agnostic.</p>

<p>This is the full quote from Bryan’s blog post:

</p>

<p>It appears that this is a different type of flashback essay than yours. The one Bryan is warning against is a flashback essay that starts many years in the future and then flashes back to the present day or to your proposed college years at MIT. So I would say you are ok.</p>

<p>Chris, do you mean to say that MIT doesn’t pay much attention to format as long as content is good?
And thanks to all for helping me out. :)</p>

<p>No, it just means that many different formats / devices can BE good if used well.</p>
