I would recommend seeing a counselor at school. There are a number of tests that you can do to see where your strengths are and what would be good career opportunities that match your interests.

I also suggest that whatever you do, to combine with some marketing/business courses, these are always useful skills. Also volunteering in areas where you’re interested in working can get you a better perspective in those fields and make contacts. I understand that your uncles likely have your interests at heart–money is important but at the end of the day do you want to be miserable because you’re doing something you tolerate with a big salary or something you love with a smaller one?
