Discernment
Act on what you control, accept the rest with serenity.
Takeaway
1. Do not waste your strength fighting the uncontrollable.
The world does not obey you. Events, others, and chance are beyond your hand.
Fighting against them is like striking the wind: you exhaust yourself without moving forward.
2. Take the helm where it exists.
Your thoughts, your choices, your actions are your domain.
Focusing your energy there gives you a solid anchor, even amid chaos.
3. Learn to say 'yes' and to say 'no'.
Yes to what can be transformed by your action, no to sterile resistance.
This filtering, simple in appearance, is the core of discernment.
4. Peace lies in clarity, not in absolute control.
When you accept the limits of your influence, serenity replaces tension.
It is this lucid detachment that frees your mind.
Origins
Epictetus, in the 1st century, opens his Enchiridion with this decisive distinction:
some things depend on us (our judgments, our decisions, our actions),
others do not (death, fortune, reputation).
The whole Stoic discipline is founded on this filter.
Marcus Aurelius, in his Meditations, repeats it to himself: to remember to refocus the mind on what is within our power,
and to welcome the rest without anger or complaint.
Stoic discernment is thus a compass: it draws the boundaries of inner freedom.
