When you are trying to get into a university, a grad school, or even a specialty school, more times than not a personal statement is required. The first thing that you need to do before you begin to write your personal statement is to write down all of your thoughts. After that is done you can begin to edit your work. You may want to believe that your first thoughts are gold, but in order to write a successful personal statement you must edit it often.
In talking to Admissions Representatives across the country, there is one aspect of a personal statement they all agree on _ BE YOURSELF and let them get a feel for the type of person you really are. This includes your motivations and the ability to evaluate your personal experiences and the effect they had on you. If you can understand that 8 out of 10 personal statements fail to do this, then you are well on your way to being 1 of the 2 applicants in every 10 that stands out.
