Open Question: I Need help deciding on a career? Suggestions?

Im an 18 year old college student planning on majoring in advertising/mass communications. The only thing is that I don't feel the corporate business type setting is for me. I Have lots of tattoos, and most of the men in my family are blue collard workers (painting cars, houses and building stuff). I don't want to do blue collard work tho, i want something different. I decided to either go into non profit work (something that i actually care about), in a advertising agency or just be at the hard rock hotel -_-, I'm also looking into fire fighting, my uncle is Miami dades fire chief...so yea
