Think of your old marketing like a literal silo that stored grain for the population but eventually became insufficient because you were getting more sources of grain. That’s why you ended up building more silos to accommodate.
On the other hand, will these silos eventually replace the oldest one? It’s like one day, you’re suddenly presented with the option of tearing it down. However, everyone’s actually grown attached to this old monument. It represented your original marketing identity.
How do you maintain your old identity without necessarily ignoring the need to maintaining the silos representing your new sources of leads?
