Do you have a vision for yourself that is not contingent to practical aspects? Imagine who you want to be ideally. From there, I would suggest asking what could you do realistically to live life in a way that brings you closest to that. You already seem to have pretty pragmatic view of life, so that should be too difficult. Lastly, ask what you can do efficiently. What are your strengths? What allows you to focus best and be the most productive?
Some people say the marketability in searching for a career comes less from your major and more from your experiences. For example, a classics major, you could still go into an archeological field (I think most study anthropology) if employers see you've had exposure to ancient from a study abroad experience in Greece.
Those are just generalizations. I am only a university sophomore, so I haven't got it totally figured out either.
