Just take some base classes your semester. Don't sweat it... You don't really need to pick a major just yet. Besides you can't even declare one until you have x amount of hours. Just take some base classes (e.g. English, math, fine arts, history, etc.). I'm a Pre-Med Sciences / undeclared major. I liked the "hard sciences" and stuck with those kind of classes. I too would try and stay away from economics unless you want to be a professor or work for the government.
