My essay was approximately the same. I made minor changes in the interest of brevity, since you are limited to fewer characters in the AACOMAS. I think the brevity enhanced my essay; I got to the point more efficiently and across more effectively. I didn't explicity mention osteopathic medicine, or my interest in it, but when you finished reading it, you are left with a delicious aftertaste that is reminiscent of osteopathy, and you understand not only my motivation for pursuing medicine, but why osteopathic medicine is a good fit for me. I also made sure to demonstrate through example some of the qualities that I wanted the adcoms to see. My essay had a story, or vignette, weaved into it.
