I have 0 IIs so far. However, I just wanna respond to your comment.
I feel like a distinction has to be made between an essay that is just "well written" and an essay that actually makes the reader go "ahh, ok, so how would this applicant apply this idea he introduces in real life or in a patient situation?"
So the things you say in your essay can't be so one dimensional or simplistic/generic - but at the same time, they can't be too over the top. Your essay, most likely, has to be interesting in a thought provoking way - that is, enough for the reader to say "I feel like I can have a productive conversation with this person on this (relevant) topic and that topic"...especially if your essay isn't literally "well, I learned this for this experience and that from that experience, and I discovered this about myself."
