Be as specific as possible. Your personal statement should include your reasons for applying, your area of interests, your academic and research accomplishments and your career goals. A great personal statement can help you get an interview, a mediocre one probably won’t matter much, and a terrible one will hurt you. You want to be unique and interesting, but you definitely don’t want to stand out too much.What they don’t know is who you are, and what draws you to your field so be straightforward in your writing. Try to avoid deep analogies, quotes, and super cheesy stories. Throughout your essay, sprinkle in skills and qualities that you feel will make you an excellent for this field without explicitly saying how they relate to the field. Length of the personal statement is also important. Keep in mind that any given program will have to go through hundreds of personal statements, so try to get your points across without all of the added fluff. Anything over one page is too much (unless otherwise stated).
In the end, do not underestimate the power of a personal statement. It is common to hear people say that it doesn’t matter, which can be true, but it can also make or break your application. Once you think it’s perfect, put it down for a few days and then revise it again. Have multiple people (friends, family, academic mentor…etc.) read it and give you feedback. Last but not least, PROOFREAD! The last thing you want to do is potentially cost yourself interviews by making a simple grammatical or spelling error. Your personal statement is an opportunity to let programs know more about yourself on a personal level.The goal is not to rewrite your resume try to explore parts of your life that are not anywhere else on your application.
