To be perfectly honest with you, I am really considering getting away from journalism period. I love to write, but I am really struggling with what I want to do with my life. And I don't know if journalism is it. Print journalism probably would be the least money making of the three. Broadcasting will work best if you are interested in TV anchoring. And advertising would probably be your best shot at making money. It just depends on what your interests are. What year are you?
