The most interesting element about what defines you is that you chose it.
We like to think that we are defined by our characteristics, virtues or some arbitrary genetic formulae. Certainly, these are all contributing factors, but what defines us is our narrative. This is something we craft ourselves, intentionally or unknowingly.
What is the single word you use to describe yourself? Is it a job title, or geography, or economic system? It could be a religion or a generation or a skin colour.
The point is, it could be any one of many things. Yet you chose a particular one to be your defining feature. That choice communicates more about what you believe is important than you may realise.
Think carefully about the narrative you create about yourself. After all, people will treat you according to the story you are writing.
Open language is more progressive than absolutes.
