Smart academic planning has a lot to do with paying attention to your growing interests, noticing how these interests coincide with LSA degree requirements, and consulting with your academic advisor. Every student is unique—a plan that works for you may not be at all what another student wants to do.
Keep in mind also that a plan is almost never something static that you determine at the start of college and then stick with throughout your undergraduate years. It evolves as you evolve through your academic, co-curricular, and personal experiences. If you arrive in LSA with specific academic and career goals, that's great; talk with your academic advisor, who will help you find courses appropriate for those goals. If you are not sure what your academic or career interests are, that also is a perfectly fine starting point; advisors can guide you by asking questions and suggesting activities that will help you find a direction.
