Consider your personal strengths. If you prefer working alone or if you consider yourself a leader, a specialization in entrepreneurship might help you in your quest to start your own business. Do you find health care intriguing? A specialization in Health Care Management might be your best option. Take an honest inventory of your strengths (and weaknesses).
Consider which classes interested you most in your undergraduate studies. If you shied away from math but loved international relations, you might want to consider an international program over Finance. It may also be wise to look at your grades from those courses, to determine which fields stimulate you intellectually.
Consider your career goals. Do you want to create your own business, or run part of an established franchise? Would you like to travel, or will you be happy settling down with a long-established corporation in a big city? Knowing where you want to be in five years will help you determine where you should begin looking now.
