Often it is helpful to begin thinking about your career interests in terms of your skills, personal interests, and natural abilities. Ask yourself why you have chosen the major you have or why you participate in student activities, athletics, etc. Are there certain aspects of these experiences that are also prevalent in the career fields that interest you? History majors go into many and diverse fields; so, keep in mind that your major does not define your career options -- think outside the box!
There are resources and people on campus available to help you discover the answer to these questions. The best place to start is the University of Wisconsin-Madison Letters & Science Career Services. Check out their website at http://www.lssaa.wisc.edu/careers/students/career_options.html
Your Undergraduate History Advisors are also available to help you at any stage of the process. http://history.wisc.edu/undergraduate/advisingandmajor.htm
