The whole point of a personal statement is to make it about your own inspirations/experiences. It can't, and shouldn't, come from what someone else has read. What do you want to highlight about your app?
Just my 0.02 cents. The hardest part of writing a personal statement is figuring out the scope of your essay. You should try to think about where to start and where to end. I spent about a week brainstorming just that. After that, everything fell in place.
