Why did you decide to enroll in college? Write your primary goal.

In evaluating your reasons for attending college, the most important step is to identify your personal goals, both short- and long-term. These should have a very strong academic component but need not be very specific.
If your interest is in literature, for example, there are many possibilities for majors and careers: Communications, journalism, English, African American Studies are among the academic fields where you can pursue your interest in literature.
In contrast, you may have a very definite career goal in mind, such as becoming a physician. In that case, the academic path is usually more clearly defined by the institution. A biology-based, pre-medical-school track may have many specific requirements. Even if your goal is specific, your education will include other options such as elective courses, so expressing your outside interests, such as playing music or sports, is also important.
You may have a passion for and excel in sports or another extracurricular activity. College could provide opportunities to pursue that, but it is useful to think about how that would fit with your broader goals. Studying business could prepare you to work later in sports management.
"I don't know" is a common reaction to a general question. College is a great place to figure out how your interests can organically lead to a fulfilling future career. If you like literature and sports, maybe writing about sports is a path you had not thought of, but sports journalism is a great career.
Finally, keep in mind that the overall goal of colleges and universities is educational. While it is true that college graduates will earn more than those who only finished high school, the goal to increase future earnings is usually not a primary reason.
