In addition to what Kate said, try meeting with people who are currently in the fields you're interested in. It sounds like you already know a bit about what you could expect, but everyone's story is different. For example, I know people who majored in something math/science related, but ended up working in the film industry. Just because you major in one thing doesn't mean you're going to end up in that field! With that being said, it can help to talk to people in the field and get a generally sense of how they got there (what they majored in, what helped them the most in college, some things you should know, what salary range(s) you can expect immediately after graduating/10/20/30 years after graduating, etc.).
