The dichotomy of control is perhaps the most fundamental principle in Stoicism. It is the practice of distinguishing between what is up to us and what is not up to us.

Epictetus, a prominent Stoic philosopher who was born a slave, taught that our distress does not come from events themselves, but from our judgments about them.

Things we can control:

• Our opinions
• Our choices
• Our desires
• Our aversions

Things we cannot control:

• Our body (to some extent, as illness happens)
• Our property
• Our reputation
• What other people think of us
• The past and the future

By focusing solely on what is within our power, we free ourselves from anxiety and frustration. If it's not up to you, it's not worth your worry.

Practical Application

Next time you feel stressed, pause and ask yourself: "Is this within my control?" If it is, take action. If it isn't, practice letting it go.
