Self-reflection is basically what these applications enjoy seeing. By this, I mean looking back at yourself and stating what you have accomplished.

I agree with Sandie in structuring your essay by selected three main points from a list that is perhaps longer. You will want to tie-in your accomplishments with reasons why you want the scholarship (why you deserve it and how you will benefit from it, and what you will do in the furture to benefit others, if you get it).
