When Epictetus talks about distinguishing between what's rational and irrational, he's urging us towards a deep, personal introspection.

It's easy to get caught up in weighing the external world's value through a lens shaped by society's expectations or immediate desires. But, have you ever stopped to ask yourself how these values stack up against your true character, your authentic self?

Think about it: the decisions we make, the paths we choose, should not only pass the test of logic or societal approval but also resonate with who we fundamentally are. When was the last time you measured your choices against this internal compass?

Applying this in daily life means pausing before jumping at what seems appealing or rushing to judgment based on popular opinion. It's about asking, "Is this truly me? Does this align with my core principles?"

Whether it's a job opportunity, a personal relationship, or a social issue, the criterion shouldn't solely be its face value or how it's perceived by others. Instead, it should also be about consistency with your character.

Decide not just with your head or by following the crowd, but with a heart deeply aligned with your true essence. That's the pathway to a life not just lived, but lived authentically and at peace with oneself.
