Mind Your Business (an excerpt from Epictetus' The Encheiridion)

Some things in the world are up to us, while others are not.

Up to us are our faculties of judgment,

*motivation, *desire, and *aversion-

in short, everything that is our own doing.

Not up to us are our body and property,

our reputations, and our official positions...

in short, everything that is not our own doing.

Moreover, the things up to us are naturally free, unimpeded,
and unconstrained while the things not up to us are powerless,
servile, impeded, and not our own.
