As a health care practitioner, you are going to inhabit a world of specifics, and admissions committees want to see that you are well acquainted with and engaged by what you do. Of course, there are going to be some elements in your personal essay that are common to most statements, but since you are an individual who has been living your own life and who has specific motivations for entering the health field there should be something about your personal statement that is fairly unique to you. You can check your statement for style, and this is where your experience as a reader comes in. Ask yourself if what you have written is too simplistic, if the tone is too cold and distant, if the humor you have included is a little out place. After you read this, you should have a better idea of what to do.
Human behavior is complex, and so is the road to a career in the health professions.
To succeed, you have to be in touch with your motivations, know where you are strong, where you are weak, how to tackle problems, and how to improve yourself. Admissions committees are often interested in knowing these things about their applicants, and to a fair degree they rely upon you to tell them. With preparation, planning, persistence, and practice you should be able to do an excellent job.
