As it stood, I think it wasn't quite the best question. But, I think there is the making there for a good-subjective question by going down one of two roads.
Path 1: We set the question more towards: what are the technical and/or artistic requirements to run a photography business and, based on my sample set, do you believe me to have those qualifications?
Path 2: I'm ready to start my photography biz, because I'm le'awesome, but I'm sure I haven't thought of everything. What are some key things that you wish you would have known before opening shop?
For those who want this site to be more about photography, why didn't we try to help OP go down path 1? Most people might disagree with Path 2, it just happens to be near and dear to me, but I get it if business gets ruled off topic.
