I suspect getting a degree in creative writing with an eye towards being a writer would be more practical than getting a degree in archaeology with an eye towards working at a university.
HAHAHAHAHAHA! *cough* Uh, anyway, I think of the creative writing degree as the "joy in the work" degree. I had three years of joy in writing and talking about writing and so on. Then I went out and got a job. Now, the dream of being a writer who earns enough to pay the bills, it is not dead, but 15 years out from my creative writing degree, I acknowledge that it in no significant way really trained me to be a writer. Or made me more likely to sell a book. So... take that for what it's worth.
