Graduate / Personal Statements for a PhD application - questions [2]

Dear Forum,

I have a few specific questions I have come accross while re-drafting my personal statement for a PhD application.

Because the application is for a specialised academic subject, I have made it very much concerned with my intellectual experience, interests, methodologies, etc (ie as opposed to too much focus on 'life changing experiences' etc). I am trying to make myself sound like a good scholar.

But, I was wondering:

1. Should I mention specific people whose books influenced me, even if they dont teach at the school I am applying to, but are leaders in their field, to show I have read widely?

2. What are opinions on using quotes in an essay like this (ie from books by the above mentioned scholars). Nothing long, just a short and snappy thing that sums up the way I look at my field, or an opinion I dispute.

3. Should I be very specific about the research I would like to do for my PhD, or broad?

4. Should I mention prizes/scholarships Ive won in the personal statement, even though they will also be listed in the application?

Thanks for the help
