Anyone who sees the world just by their own limited perspective, without wanting to see it from a third-person view, lives in a one-dimensional reality.
In such a scenario, everything is perceived just by that individual’s viewpoint.
So thereby, their biases and their narratives decide the outcome of a scenario even before it happens.
Whether this is through conversations, or actions, with people, or with generic scenarios, how the world reacts to them and how they react to the world is pre-defined in this one-dimensional reality (and it always goes the same way).
To broaden one’s horizon and to widen their perspective means to accept this reality they live in and then wanting to not that way.
