Thanks for all of the great advice.
A lot of people seem to think that being older can be a pretty big advantage, and definitely outweighs it being kind of awkward once in awhile. That is pretty reassuring.
Due some advice here I also realize that I should be casting a wider net when it comes time to apply for grad school. My goal is to get into one of the top three tiers for grad school. According to the American Economics Association, they are:
Tier 1 (ranked 1-6): Chicago, Harvard, MIT, Princeton, Stanford and Yale
Tier 2 (ranked 7-15): Columbia, Michigan, Minnesota, Northwestern, Pennsylvania, Rochester, California-Berkeley, UCLA, and Wisconsin-Madison
Tier 3 (ranked 16-30): Illinois-Urbana, Boston University, Brown, Cornell, Duke, Iowa, Maryland (UMD), Michigan State, New York University (NYU), North Carolina, Texas-Austin, Virginia, California-San Diego, University of Washington, and Washington University in St. Louis (WashU)
So in my home state, that is Michigan and Michigan State. I was including Western Michigan as kind of a back up plan in case I can't get into my preferred schools. However, due to some advice here, I am thinking I shouldn't have such a narrow view, and applying out of state to some of these other schools could be beneficial to me. Of course, I have to focus on doing the best I can in undergrad first.
