One-size-fits-all marketing is as effective as a one-size-fits-all pair of jeans.

Imagine a pair of jeans that’s meant to be worn by males and females, children and adults, tall people and short people, thin people and fat people – it’s not going to be very comfortable.

You know what’s just as ineffective?

A marketing campaign that’s meant to be consumed by young and old, rich and poor, trendy and conservative, and every other type of customer.
