Most importantly, remember that most people don't end up working their whole lives in the career their college major pointed to. In fact, many work in jobs that didn't even exist when we were in college! If you develop your own skills and strengths, you'll find many different ways to apply them. Curiosity and a problem-solving mentality can lead you naturally along from one opportunity to the next.
I have a friend who got a B.S. in nursing. While working, she became interested in (and qualified for) critical care nursing. From there, she learned about being a perfusionist. She went to grad school for this, and then while working as a perfusionist, developed specialization in pediatric perfusion. It was a natural and logical path that she found rewarding.
I majored in news/editorial journalism, and got an entry-level job in PR for a software company. PR reported into the marketing department, and when they found out I could write, and understood the product and customer, soon I was writing everything from news releases and case studies to brochures and annual reports. Eventually it led to several jobs as VP of marketing for startup tech companies.
So, start with what you naturally like and are good at, and see where it leads you. Best of luck!
