How to get an identity
You purchase it.
As easy as that. At least in this day and age. You can be part of anything just by getting some merchandise with the desired lifestyle brand.
In the past, the identity was deeply intertwined with what you did and where had you born. If you born in a locksmith’s house, chances were, you would end up acting, speaking and even dressing as one. Because you became one.
Even further back, the tribe would set the position you would take within it to ensure the survival and the prosperity of the community.
Now you can choose your occupation, fortunately. And in that choosing, your context, your belief system and your hopes and dreams will drive you to the road of desire. You will desire those things that give you evidence that you are part of a certain group and you will try to adopt the culture of said group.
So, again, we buy stuff that help us create and reinforce the narrative of ourselves that we want to portray to the world, including ourselves.
