I have taken multiple courses while in college that have not been in the field of my major, Historic Preservation, but have nonetheless given me valuable skills and knowledge that will be useful in a wide range of fields.
I have taken a couple literature classes, notably Shakespeare and Popular Culture and Global Issues in Literature. In both I completed projects in which I analyzed texts and formulated an argument based on the readings and on outside sources. You can view a sample from Shakespeare and Popular Culture here and a sample from Global Issues in Literature here.
The most important skill that these courses taught me was to think critically. Reading and analyzing literature taught me how to ask the right questions and how to search for the answers. This is especially relevant to Historic Preservation due to the amount of research that is done in the field.
