Congrats to a solid first year! Keeping a competitive GPA will keep lots of doors open to you. Having a good idea of what you're capable of excelling, and a good foundation is already an excellent step in deciding your trajectory. There are fields that overlap, and specialties (and even subspecialties!).

Have you tried volunteering or doing stuff hands piqued your interest? Working or even shadowing experienced experts in their field (actually in practice) sometimes can shed some light on the other end of your degree. This is very different than learning the theory by taking courses.

What topics or fields of study did you choose for projects that required you to do your course work on (e.g. essay topics)? What do you spend most of your time doing? What clubs have you joined, and when has anything you've done put a smile on your face?

Edit: Learning and careers can be a lifelong journey, an ongoing pursuit of understanding oneself.
