The materials are indifferent, but the use we make of them is not a matter of indifference.
EpictetusNothing outside the will can hinder or harm the will; it can only harm itself. If then we accept this, and, when things go amiss, are inclined to blame ourselves, remembering that judgment alone can disturb our peace and constancy, I swear to you by all the gods that we have made progress.
Epictetus
