To halt of our own accord

Seneca, On Tranquility of Mind, X 6:

Nothing can free us from these mental waverings so effectively as always to establish some limit to advancement and not leave to Fortune the decision of when it shall end, but halt of our own accord.

Foucault, The Care of the Self, p. 93:

And to Lucilius, who is not under any threat, however, Seneca gives the advice to disengage himself from his duties, gradually and at the right time, just as Epicurus counseled, so as to be able to place himself at his own disposal.
