The Flinch: What to Do With the First Jolt of Anger or Anxiety

The first episode of the One Passage series introduces a simple Stoic practice rooted in Seneca's Letter 11. Seneca notes that even the wise blush, sweat, or flinch involuntarily—the first physical jolt of anger or anxiety is not under our control. The exercise asks listeners to notice that flinch once today, name it, and note whether they caught it, even if only after the fact. By repeatedly observing the involuntary startle, we learn to separate the automatic reaction from the conscious response that follows.
