I initially looked at a few general PS to get into the mindset of what a good PS shares across different subjects
I then went onto the TSR personal statement section and opened every single one for my course. I then opened every single one on studential. I looked at about 60-80 and closed off the ones that I couldn't relate to at all and narrowed it down to about 20 and then looked at those more closely and saw what was good about them, the way they phrase things and their structure - how they address key points etc and used it in mine.
To proof check your PS for plagiarism just copy your PS into google, one line at a time. Mine seemed to be very personal as I couldn't find a single line / phrase on the search engines, but even if some of it is vaguely similar and Google finds something similar, it will be dismissed as UCAS knows that over the years some statements will have similar phrases. Obviously if this happens for more than 3 lines I would change it.
Just keep it short and real concise, get to the main points and do it quick. Admissions look over hundreds of these things in a day and they're not looking for flowery language; they're looking for candidates that are capable of their course, with enough passion and desire not to drop out in the first year.
Also my biggest advice is not to worry yourself to death. Just do your thing and ideas will pop into your head, note them down and take it a bit at a time if you have to. Main thing is to write something that you can later amend, even if it's bad to start with.
