It has been my experience working with college students that it's often difficult for them to commit to one college major. Of course there are those students who know exactly what they want to do after college whereby choosing a college major is no problem for them as they can do the research to see what courses they need to reach their future goals. Students often come in to my office feeling that all of their friends and everyone else in their class knows exactly what they want to do as a career; and therefore, there must be something wrong with them if they still find themselves to be undecided.
One thing that is important for students to keep in mind is that they can pursue many things with any college major. When I hear seniors say that they are frustrated because they've picked the wrong major, they often perk up when I quickly point out that their college major does not prohibit them from choosing a career that may seem to be unrelated.
The important thing to identify is your knowledge, skills, interests and values. Just because you majored in English doesn't mean that you are bound to only become a writer. Going to college provides a framework for developing skills and finding new areas of interests, but it does not preclude you from pursuing a job in any field of interest. As a new graduate you can always choose to go back to school and take the required coursework to get a job of interest or even go on to pursue graduate school to help you meet your future goals and objectives.
