"Running a business" is what i've been trying to do this time around, however I've found out that if your model relies on one or two sources for revenue, it can easily fail.
If you want this to be a business then you need to approach it like a business. First step: determine what business you are in. Next steps: determine what your product(s) is/are; what your market is; what market segment you are going after; who your customers will be; why they will buy what you are selling; what your revenue potential is; what your expenses will be, etc.
Then determine what your dependencies will be and what the risks are (things that can come out of nowhere and screw you). May want to do a SWOT analysis of the business you want to build - Strengths, Weaknesses, Opportunities, Threats. You can find lots of online info about this.
Or you can careen from from one Google hosing to another.
