I'm thinking about going to college for Photography as my major. Is it worth it, or maybe I'll be better off taking some classes and learning on my own?

O.K, so I'm only 15, but I like photography and would like to peruse it as a career someday. I have a decent digital camera, It's a 5mp camera with a 4x optical zoom and a pretty decent lens. It's just a point a shoot, but I didn't have $700 to spend on an slr. I've read a book that taught me about aperture and iso and stuff. Anyway, can photography be a potential career? What could I do, if it made decent money I would like shooting weddings and events and stuff (I like candid photography best) but am willing to explore other options. Know, since I'm only 15 I know I wont be making any money for awhile but what can I do now to prepare for later? I mean like practising my photography. Oh yeah, I am decent at editing my photos and have Paint Shop Pro. So, yeah, what can I do know and what should I do later?

P.S
You don't have to tell me that your not going to be able to do photography full time starting out, I know that photography would have to be a side job.
