Personal Statements!!

Hello,
I am a graduate physio looking for a job. I am currently working as an HCA for a palliative care home support team. I am finding it difficult to secure my first physio post as are so many others. I was wondering if anybody can give me any tips as to what to put into a personal statement (Supporting information). All online application require this and it is the one part that separates you from hundreds of others and i just dont know what standard mine is or how to improve it. I'm really stuck so any helpful tips would be appreciated. Does anybody have an example of a good personal statement (supporting information)?? Although it will be very different from mine it may show me how to make my own one read better.

Thankyou!!:o
