So, you will badly hurt your chances of getting into your dream school if you try to be someone else. Just be yourself, and write only about the things that have happened to you, and the things that you are passionate about. Saying “I love research” just because you think they will like it, isn’t going to help you a lot. Whatever you say just for the sake of it, won’t appeal much to the committee, as they would look for relevant evidences in your stories and in your past . So, don’t even think about fooling the committee with a false storyline. Try and be yourself throughout the essay.
