I love phot and want to incorporate it into my major that I choose in college, but I feel stuck by how much money it makes.

Do what you love and is your passion and work will never be a drudgery, boring or a mistake - the money will come. But If you work for money but hate your job you will be miserable.

get a liberal arts degree

Photography, like any other art, is something you do because you can't imagine doing anything else. And, like other arts, you just hope that others like what you do. If they do, you do well financially.

Also, like other arts, there are several ways you can express yourself. You can do abstracts, landscapes, portraits, fashion, news, commercial, stock and, I'm sure, other approaches that people will pay you for.

The solution is for you to take as many photos as you can of as many different subjects as you can. This is how you learn both photography and what you're good at.

Meanwhile, become a "renaissance woman," with as broad an education as possible. My advice is to pursue a liberal arts college education (and a degree) while finding as many ways as you can to photograph whatever you find interesting. ALL knowledge will be useful to you at one time or another during your lifetime.

Get a job with the college newspaper or yearbook, whether it's paid or not. Offer yourself as an intern to a local photographer. Find ways to learn as much as you can about as much as you can. It's fun!

You definitely want to carefully consider your major. Business and/or marketing would be good matches to compliment photography. These areas are tough for photographers who do not have a formal or strong understanding of the business part of photography.
No doubt it will take time to get established, even if you are working for a company that will be using your photo skills. Practice the basics of photography - lighting, composition, design until they become second nature to you. On-line guides such as CreativeLive.com can be a treasure of information for you at this point. Financially, of course how successful you will be depends on your motivation and the market base that you are working.

I would follow your heart. The money will come if you are good enough and want it. You can be great and happy if you do what your heart says.
Don't chase money, it will not make you happy in the long run, but your dream job will .
