We all want to be accepted.
It is just that, we all want to be accepted by different people, for different reasons.
When we grow up, we want to make our family proud of us. This is something that we share with most mammals. The kids in the litter defer to the adults.
What makes humans different is our ability to grow up and develop a want to make us proud of ourselves.
Some of us get it rather early. Some of us reach that stage in our early to late adulthood, even during our twilight years. Some of us completely miss the urge.
We all live our lives out differently as a result. We develop our own tribes and customs to identify and commune with those who think our way is right. In that process, may of us have no problem in turning away from the tribe that we are born into and finding groups where we belong.
And therein lies the essence of all advertising and marketing. It is about making me want to belong to a tribe that I want an admission ticket to. It is also about making stronger bonds within the tribes that I love.
So sell to me - sell to me my identity; sell to me my aspiration - if you will not, I will not buy your product.
