Lauren J.’s Answer
Network, network, network! When you are in school you are being taught by professionals who have most likely been in the profession for quite a while and know lots of other professionals. Reach out to professors and ask about opportunities to get involved in research projects and/or ask about job opportunities. It is best to get relevant experience before you graduate--you won't necessarily be doing exactly what you hope to be doing once you get the degree but a lot of related jobs will at least give you insight into what "after the degree" might look like.
Also, use any resources offered by your college -- ie. career services, academic advisors. Ask them about potential career paths for individuals with your degree. Try to get in touch with Alumni (you can do this on LinkedIn too) and see what they are doing now they have the degree you are going to have.
Best of luck!
