What's up to me

Epictetus was born into slavery in the first century, in what is now Turkey. Even his body wasn't his own: one old story says his master twisted his leg until it broke.

He later gained his freedom and became one of the most influential teachers of Stoic philosophy. His student Arrian wrote down his teachings in a short handbook, and it opens with the idea that runs through everything Epictetus taught.

Up to us: our judgements, our intentions, how we prepare and how we respond. Not up to us: other people's opinions, the weather, the past, how things finally turn out.

Worry spends most of its energy on the second list, rehearsing outcomes we can't decide. The Stoic move is to gently bring that energy back to the first list.

This isn't giving up. Acting on what is yours is often the best influence you have on everything else; you just stop holding yourself responsible for the parts you never controlled.

• The Serenity Prayer

  Courage to change the things I can, serenity to accept the things I cannot, and wisdom to know the difference.

• Islam

  "Tie your camel, and trust in God": do your part, then let the outcome go.

• Psychology

  Problem-solving ends in an action you can take; worry circles outcomes you can't.
