Anything you mention, then, should be unique.
The way I would do it is to build up to where I mention my educational goal--and have that as a thesis. "I had known since early childhood. Oh how sublime it was--how obvious. I watched my mother peel a potato in the old breakfast nook of our cononial home in Westchester. A potato. The embodiment of agriculture,the foundation of civilization. I was to be a farmer--a potato farmer.
Then I would work in how I went about choosing and narrowing-down the prospective list of schools. For example, "I have Idaho in my blood; I have always fantasized about going there. Thinking about Idaho makes me shiver--the kind of warm shiver one experiences when hearing his favorite song over he radio. The American heartland of potatoism--a potato Mecca. Choosing to attend a college anywhere else was simply not an option.
Then go on to talk about what your college offers that others don't: "Study abroad in Ireland. The motherland. The old country. I knew--that moment--I knew that the University of Idaho was my destiny. In the days and weeks that followed, the University of Idaho had merged into my own sence of identity. I watched to virtual tours online hour after hour, memorizing every feature of the landscape, every hall. Every waking thought...."
Hope I helped.
