Most creative businesses are built around a single individual -- whether a name designer, planner, or photographer. As the business grows, the capability of that individual to do it all becomes impossible (or incredibly stressful) even with an assistant or two. When this happens (and, hopefully, it will (or has) happened to all of you), you will have to decide whether you want to remain an entrepreneurship or become a business.
Entrepreneurs have a very difficult time letting go of any part of their business. Their operations are structured in a way to make sure they are involved in every decision and nothing happens without their input. Think Jimmy Carter scheduling time on the White House tennis courts. Most often, they are surrounded by people who are functionally capable, but managerially challenged.
