There is nothing wrong with discussing common and everyday issues, but your essay might not have something new to offer when you stick to these topics. As far as the admissions officers are concerned, it is just another boring document among hundreds of other application essays. You do not need to write like John Grisham with suspense in each and every paragraph, but to turn in a top notch essay, you have to show them that you are an original thinker. Come up with fresh insights, and chances are, your essay would impress them so much that they’ll call you for a face-to-face interview. Avoid cliches and be more creative when detailing your reasons for wanting to become a doctor. Don’t just say that you want to help mankind, but provide specific information.
