Labels mean nothing without action.
There is nothing more which makes it clear which individual is than through the actions which they take.
It is important that one recognises that a label and status are mere constructs which are built on changing perspectives. Ultimately what it concrete is the physical actions which an individual takes, in every moment of their journey.
A wise man once said:
Judge not an individual by the actions taken in the presence of others, but rather through the actions they take when on their own
It is the actions and the results of those actions, which lay the foundation for who an individual truly is.
