A Personal Meme is an oxymoron.
Memes are not personal to an Individual.
They are common to a society.
A society is a collection of Individuals.
When a collection of Individuals holds the same belief, it becomes a meme.
A meme is not a collection of beliefs.
A collection of memes is called a culture.
Memes determine how a culture grows.
They are the blueprint for the growth of an Individual that is determined by a society.
People do not have an individual culture.
They adopt the culture of their adopted society.
I can be born into a society and adopt their culture as mine, or I can abandon my inherited culture and adopt a new society.
I adopt a new society by adapting to their culture, beliefs & memes.
Having adopted my cultural memes, I may own them but they are never unique and exclusively mine.
