B.A. in Spanish -- I don't regret my major one bit at all. The best part...study abroad! Oh, and I can watch Spanish films and understand them pretty well. Actually, Spanish has opened up more doors and opportunities than I even thought possible...and usually happens in the oddest ways possible. It also really helps that there's a large Hispanic/Latino population where I live.
I will be finishing up a M.A. in TESOL (Teaching English to Speakers of Other Languages) pretty soon, and I've learned a lot about language structures and language acquisition that is both research-based and anecdotally-based. It's taught me teamwork and teaching skills, and possibly most-importantly, has taught me to care more about people and empathizing/sympathizing with them while meeting them at their point of need. I've learned to think more critically, and have honed in on writing and researching skills. Overall, I can't complain. Yes, you go through A LOT of BS in order to get your degree(s), but hey, I guess it teaches perseverance and patience too.
