I started off as a fine Arts major, changed to Communications at 2nd semseter soph year, changed to Creative Writing beginning of junior year. All that changing made it take longer for me to graduate, but I don't regret it one bit, as I learned so much in my CRWT major that I use now. I write for a website, and am writing a novel and screenplays--so that was definitely where i needed to be!
Major in what interests you. You'll learn more and do better.
I've changed fields 3 times since college--started off in advertising as a copywriter--which is what i thiought i wanted to do when I was in college, and I liked it, but... was drawn to film, so worked in flim industry in various capacities for several years before switching to dot-com--albeit a film industry dot-com...
what I'm trying to say is, you probaby won't end up doing in 10 years what you now think you'll be doing--so study what interests you, learn a lot, have fun, and worry about it when you graduate.
