I have had many ideas over the years and finally want to take the risk of starting my own business. However, my ideas do not fall into the same industry although they have an overriding theme. I would like to start a business that seeks to bring all these ideas to fruition over time, one by one. How do I write a business plan for this company without overcomplicating it or should I be attempting too write a business plan for each one of these ideas once I get to them eventhought he company is the same.
