Not everyone wants to buy what you’re selling.
Do you really want someone as a customer if they don’t see the value of your product?
Sometimes it’s an information problem. Sometimes there might be some initial resistance when they don’t quite understand what it is you’re offering. Sometimes they might not see the intersection between your services and their aims.
Beyond that it becomes wasted effort. You’re simply creating more problems. Yes you might eventually convince them. But at what cost?
Think of places you could better spend those resources.
Serving the people who really want it.
