Sam uses the word equanimity quite often in his podcast, and most recently in episode #205 of “Making Sense” with Daniel Markovits.
- evenness of mind, especially under stress
- mental or emotional stability or composure, especially under tension or strain; calmness; equilibrium.
- calmness of temperament; even-temperedness
- the quality of being calm and composed
To me, this word sums up Sam’s personality quite wonderfully, actually.
