Hi Brandon, I'd recommend looking into internships or volunteering in your area in your spare time (perhaps during the summer or even on the weekends). Try out different positions in the fields you are most interested in. This will give you a good idea of the field you're interested in as well as specific roles within the industry. Also, consider the reasons why you have joined the groups at school that you are involved in. For example - take debate and forensics, do you prefer the social aspect to being involved in these clubs or do you like being presented a case and looking at it in an analytical way? If you look at the activities you enjoy you'll often find a common theme which could be helpful when looking at careers as well.
Just from you describing what you're currently involved in, I would recommend looking into Communications or even Marketing. These fields often offer creative freedom while also allowing you to learn more about business and branding.
