As a student interviewer, please please don't feel like you need to fluff up your PS. I see these personal statements sometimes that have alot of fluff in them and they annoy me because they take me extra time to read no information. What I'm looking for when I read your personal statement is your motivation and preparation for medicine, what you're about as a person, and any unique or interesting things I should know about you.
Two resources I found useful at UDel were both the English Writing Center (down in the basement of the English building), which reads statements for professional schools for grammar/structure, and Dr. Schmieg. If you set up an appointment with her to review it, she's helpful because she's got a pretty good handle on what adcoms are looking for.
