Lovely piece, though there is a significant section missing about when in a business’s lifetime these rules should start applying. Most of the business functions (like support calls) should not be automated and doors should be kept open, as long as the key decision maker has bandwidth.

E.g. don’t hire an accountant until you can’t do it yourself. Feel free to answer random unsolicited messages until you have no more time for it etc.

Running a business is not a matter of defining these principles up front, but letting efficient process emerge from need.
