I agree with Rebecca above, there are a lot of jobs/careers where the training is done on the job, but the degree/major gets the person in the door. Many majors are transferable to several different jobs and lead to different career paths. I majored in accounting and finance, but only about one third of my job responsibilities relate to technical accounting. The rest relate to project planning (determining the appropriate staffing, planned timing for projects), preparing and giving presentations on various topics (not directly related to accounting), giving trainings to develop the skills of others (again, not directly related to accounting), I provide the on the job training many times. Overall, I would not worry about choosing the "wrong" major, even if you complete college and obtain a degree, you most likely can find many different types of jobs with the degree and once you are in a job, you may be able to transition into a different type of role not directly related to your degree.
Best of luck.
