Essays / "Reasons for wishing to work with a particular group"; Suggestions on how to write [3]

Hi everyone, I'm applying a scholarship in the UK.

There is a question "reasons for wishing to work with a particular group" no words limit...
Any suggestions on how to write and is two pages too long?

I'm thinking to start with my childhood in a Asian culture ( spoon-fed education system),then how the education system in the UK is different and how the professor motivates me and finally the reason I want to study in that uni and the group (i.e. like research interests).

Is this ok or too personal? Thank you for your help!!
