How to write a medical school personal statement: Motive _ Third is having a compelling motive. It's the underpinning of the whole essay. Unless you speak to a compelling motive, the default result from the reader's point of view is this student is writing a general medical school essay, but doesn't really know why. You've got to be willing to flaunt the motivation and be really willing to shout at the top of your lungs standing on a chair in the middle of a crowded auditorium. Be THAT committed to what you have to say. All of this sounds incredibly unrealistic and incredibly overdone, but once you put these concepts down on paper, the very act of reading mutes so much of the impact of language, that you've got to be willing to trust that you can be very committed and very over the top in how you articulate, and it will still carry off.
Being an Apologist _ You do not use your personal statement to explain why you lack certain skills or experience. The point of writing this short paragraph is to sell yourself and this involves highlighting your strengths instead of apologizing for your weaknesses which in itself is a sign of weakness. The time and place for discussing flaws in your suitability is the interview and at that point, you must focus on how you plan to overcome any holes in experience/skills etc.
