I don't know what to do with my life?

I'm a Junior in college studying Sociology. However, I've always noticed since I was younger that I love photography. I know photography isn't really something that you have to do young to be successful, as many photographers see success well into their life. However I was wondering what are some ways to get into photography. Also, what are some Master's Degrees (Farthest I can afford in terms of education) that I could get that are pretty versatile that I could work a lot of places. Someone told me marketing would be good if I wanted to do photography. Thoughts?
