Cougar,
The point is, do what YOU'RE interested in. If you want to major in a language, do it. If you want to do a minor, do it. BUT don't expect to get fluent from it, even if your just taking grammar classes. And don't expect anyone to be uber impressed with it. If you're doing it to impress people and you don't care to learn the language, you will miserable. I've said before that I took five years of Spanish classes and it impressed NOBODY. Thank goodness I liked it for myself. Furthermore, I learned little from sitting in class (literature or grammar focused) because it's different from the way people normally use the language; knowing the exact structure or grammar doesn't do much either. Most native speakers of any language, English included, don't know exact grammar that you're taught in class... they just know what sounds right and what doesn't, naturally. I learned more interacting with people who spoke the language.
Think about it. The English classes you took in high school or college....the ones that made you read Shakespeare or analyze the metaphors in "I Know Why The Caged Bird Sings"..... how similar is it to the way people normally speak???? Not much. You can't be quoting Don Quixote or Voltaire or Mein Kampf to your patients. They will look at you like you're crazy! It makes you well rounded intellectually, but not fluent.
