Every semester, the lists of available classes go out at registration. Posters start to appear on the bulletin boards. Maybe you'll even see an email or twitter announcement. How do you choose?
For many business majors, the top reason is eventual employability. A skill (language, writing, communication, presentations) that can add something to the resume often rises to the top of the list. Today I heard from UNI's Professional Writing Program where writing projects are done for real clients...always a good resume item...and pre-requisites can be "easily waived." If you've got a professional skill area that you'd like to develop, be proactive about finding ways to get 'er done!
But, don't ignore other aspects of your personality. Global corporations also appreciate employees who actually understand world history, international politics, and non-Western cultures. Manufacturers like to hire folks who have a basic understanding of the science that goes into making their products. A sales professional will certainly be more successful with a grasp of principles taught in basic psychology, sociology, and cultural anthropology courses.
In fact, a course in personal wellness that teaches stress reduction or healthful nutrition might make a big difference in your professional attitude!
