Hi Driekus!
I can recommend a few good resources:
1. When I was applying, I used mbaMission's (free) personal statement guide to help me frame my letter of intent, or goals essay. You can get that here:
https://www.mbamission.com/docs/mbamissi ... _guide.pdf
2. I also really like the book, Your MBA Game Plan, as a comprehensive guide to the process. They also have great advice for your personal statement.
Since applying, (and getting accepted to Wharton, Columbia, and Tuck), I've started my own admissions essay editing service, My MBA Story. If you'd like me to review your letter of intent, I'd be happy to. What schools are you applying to?
I also write a blog at
https://mymbastory.tumblr.com/, which has some free advice.

I recently wrote a post on how to write effectively about why you want to go to a specific school (an important component of your letter of intent for each school). You can read that post here:

Feel free to e-mail me if you have additional questions, and good luck!
