There is a book by Michael Gerber that nearly every actual and wannabe entrepreneur should read called The E-Myth. (NOTE: The book’s actual title is “The E-Myth Revisited: Why Most Small Businesses Don't Work and What to Do About It.”)
Overall, it is brilliant. One of the main points of the book is that one main reason that it’s so hard to be a business owner is that it requires us to be three (3) people: a technician, a manager, and an entrepreneur. Most of us are only one or two or these, but a successful business needs all three of these elements.
My slowly developing experience thinks this is brilliant and accurate.
However, I realize that there is one missing “person.”
