It is a too verbose text for my tastes, so I will summarize it for you:
People usually start a business with a technician mindset but a successful business requires balanced entrepreneur, manager and technician roles.
- Entrepreneur: What do people need? How much would they pay for it? How will they know about my product (marketing)? What is my future vision for the company and myself?
- Manager: Provide structure (processes, manuals etc.) to the organization.
- Technician: Check technical feasibility of product ideas, build products.
Each role requires the same amount of time and attention. The main reason for business failures is that their founder is not aware of this and is stuck in one (usually technician) role.
