I have seen this come up a lot. What magic stuff do they teach you to run a business in school?
The point is that in many cases, but certainly not all, photography is a gateway to running a small business. And as such, your success or failure will largely depend on your skills in business, as much or more than your skills in photography.
So, while it would probably depend on the type of photography you want to do...it might be a good idea to concentrate on the business side of things for your education. And on the plus side, business education is a lot more universal, and could help you to succeed in almost any field, not just photography.
