What sort of things should I write about for my Business Administration PS?

Hello.

I have wrote around 5 drafts (more if you count for minor grammar changes) for my personal statement. I have included many topics that I love, but still am unsure whether my PS will be enough to get an offer from University.

This personal statement is due in January, but I tend to be very organised and plan everything well ahead.

I've done things such as:
- MD in Young Enterprise
- Read books on the topic of Business
- Done martial arts
- President of the School Debate Club.

I'm particularly interested in getting into the University of Bath, but the admission rate is only 10%. That is, unfortunately, the only University I want to go to. I've gone to other open days (I went to Bath too), and seriously, the only place that felt right was Bath - both course wise and living wise.

I don't know whether or not they'll accept me.
I'm also from another country within the EU so I'm very unaware of whether that would be something good to talk about as I know Universities value other nationalities for their diversity.

Thank you
