Talk to your advisor or come to the Counseling and Career Planning Center to get some ideas. With some exceptions, undergraduate degrees do not necessarily determine your life's vocation. If you survey mid-career professionals in most areas of the work world you will discover relatively little correlation between what many of them are doing now and what their college majors were. There are some important exceptions to this rule, however, so don't make any major decisions without proper research into the career field you are considering. Also, this is mainly true for undergraduate majors.
Graduate degrees are generally much more focused and require clearer definition of career goals.
