Undergraduate / my motivations and aspirations for going to NJCU essay [3]

I'm having some trouble. I need to write a 250 word or less essay. The topic is my motivations and aspirations for going to NJCU, also to tell them a little about myself and my interests. I can't seem to figure out where to begin? Does anyone have any tips that might help me on how to get started? I usualy have no trouble writing except for the beginning that always seems hardest for me.
