In order for there to be tension in your personal statement, it will help to describe a highly charged incident, part of a particularly difficult period in your life. Whatever it was, you will maintain your reader's interest for that much longer. The example below shows perfect tension and suspense build up _ "When the airmail letter arrived bearing an American stamp, I knew immediately, it was from my university with my degree results, and I tore it open as excitedly as if it were a birthday present. With trembling fingers, I took out the sheets of thin blue paper _ and my heart started to pound as I began to read."
Remember, your personal statement is 'personal' in nature so it is in your best interest to be sure that all the information you provide is in fact your information. By starting with one sample and taking some ideas, then moving on to another and taking additional ideas, and so on, you allow your true self to come out in the finished product and this will give you the best shot at gaining access to the school of your choice.
