Most small businesses are started by technicians who assume that because they understand the technical work, they understand a business that does that work. These are entirely different skills, so the technician ends up owning a job they're bad at managing rather than a business that runs without them.
Every business owner contains three competing personalities: the Entrepreneur who envisions the future, the Manager who craves order and systems, and the Technician who wants to do the work now. A healthy business requires balancing all three, but in most owners the Technician dominates and suppresses the other two.
Build the business as if it were a prototype for thousands of identical franchises, documenting every process into systems so the operation depends on systems rather than on any individual's skill. The goal is a turnkey enterprise that can be run by ordinary people following defined procedures, freeing the owner from being personally indispensable.
