Attention on something that is not yours

Epictetus, Discourses 1.25.4 – [Hard translation]

Whenever you devote your attention to what is not your own, you lose what is truly your own.

Another translation:

The more we value things outside of our control, the less control we have.

Remember the Serenity Prayer.

Is this in the “courage to change the things I can” category?

If not, pay it no mind.

Devoting attention to to “the things I cannot change” means losing what is truly mine — “the things I can”.
