The essence of the healthcare business is “doctoring.“
If you have no physicians doctoring, you will have no patients, no nurses assisting, nothing to market, and nothing to bill. Without doctoring, nothing happens.
The essence of the writing business is writing.
If you have no writing you will have no books to sell, no agents to reach out to, no publishers to find, and nothing to sell. Without writing, nothing happens.
Put the essential—the essence—first.
