Enkrateia
ἐγκράτειαen-KRAH-tay-ah
The mastery of self through the power of will over impulse and appetite. For Aristotle and the Stoics, enkrateia represents the disciplined control where reason governs desire, distinct from sophrosyne in that the struggle against temptation remains consciously felt.
Modern Application
When you feel the pull toward distraction, comfort, or the easier path, enkrateia is your capacity to choose discipline anyway. You strengthen this muscle each time you act from principle rather than impulse. As a leader, your self-command becomes visible to others and sets the standard for what's possible.
