I am actually a freshman right now at UM!
Getting into Michigan won't be great, it'll be a-Maize-ing.
^Funny, but this shouldn't be in your essay.
I was a little confused throughout your essay. I don't get how the guest speaker has to do with anything and neither do you apparently:
I have often wondered if our guest speaker had somehow hypnotized us into becoming suddenly obsessed with the study of the brain.
Maybe you should cut down on the intro since I don't see what you're trying to do with it and maybe talk more in depth about how psych intrigues you.
Whenever I had a random thought, I would instantly try to figure out why I had that thought. I could usually figure out where it came from, and thus figured that there really is no such thing as a random thought. I sadly noted later on that someone had already come to that conclusion. I hammered these "hobbies" so well into my head that I could pick up on anyone's mood in an instant.
^I don't think that you're really explaining what you want to explain here. Maybe take some more time in developing this section.
Maybe you're dissatisfied with current contributions to the field of psych so you want to bring yourself into the area. Maybe you feel that many of your ideas are already a part of psych and you want to know how much stuff there is to learn about it. It'd be nice to know what you plan to do with this information.
I like to think about thoughts and U of M has the 2nd best department for thinking about thoughts is probably not enough.
In my heart though, it's first.
