I've got a friend who is an anthropology major. He loves it, but he really has to get a master's degree to be able to employ himself with his degree. He's not really interesting in doing the "go out, find a tribe, live with them for the next 2 years in the middle of nowhere" sort of anthropolgist.

Don't take me wrong, doing what you love is great, but you've got to take that look at what you'll be making etc..and figure out if you can live with that. That doesn't mean you have to decide right now though. I went from biology to electrical engineering. And if I'd been this interested in reptiles when I started college, I would have gone the exotic vet route.
