First off, congrats on your acceptance! I'm going through the application process now and finding it challenging to do my best to present myself. I have my applications edited by an editing service Paper Editing & Professional Proofreading Service | Edit My Paper because I find it helpeful and they give good advice. I also ask friends who already got in what they suggest for each application. I'd say being persistent with asking other people for help (or paying for it) can benefit you in the long run, even if it's annoying to who your asking.
