Some people here posted their personal statement on their MDApps profile. A couple people in the non-trad forum did too recently.
I agree with music2doc, there are people who will probably just plagarize if given the chance, which is very unfortunate. In addition to his/her advice, I'd also suggest not focusing so much on "being unique" in your essay. With tens of thousands of applicants every year, there just aren't enough unique themes to go around 😛. I'm guessing that most people's personal statements have similar themes anyways (e.g. wanting to help people, fascination with human body and/or a certain disease, personal or family health issue, etc.).. So focus on showing what brought you here, what's important to you and what motivates you. After reading your personal statement, a stranger should imo be able to answer why you want to pursue medicine.
I'd also suggest not becoming obsessed with any particular draft, especially your first one. I don't know about other people, but I went through many drafts before I wrote the one that I ended up using. Ironically, this final draft took the least amount of time to write. My earlier drafts focused so hard on "being unique" that it actually ended up sounding fake. So write away and see what sticks.
Just my thoughts 🙂
