I dont really know what to do with my life. I love to argue, and if I could make up my mind and set a goal I would reach it.
One of the pillars of ancient Greek education was rhetoric/ sophistry. Maybe try a debate club?
I agree with some others that enjoying debate doesn't necessarily mean you should become a lawyer. My $.02 is to pursue a nonspecific, liberal foundation with a view to seeing what interests you and what doesn't. Expose yourself (heyyooo!) to a broad range of subjects and follow your nose when you find a subject you like. Use the internet and independent study to discover the fields you enjoy, as well as the curriculum and faculty of your uni or HS.
Imo, do not pursue a field of study because you think it will help you make money. Study something you enjoy and make money with that.
