Here's something that reframes the Saturday workout you might be debating: the ancient Greeks had no word separating physical training from mental discipline — 'askesis' meant both at once, and it's where we get 'ascetic.' The Stoics borrowed it, but it originates in athletic culture, where the body's resistance was understood as a direct teacher of the mind's capacity. Psychologist Angela Duckworth's research on grit found that deliberate practice in physically demanding domains builds the same neural tolerance for discomfort that shows up later in professional persistence — the gym isn't a metaphor for hard work, it's literally the same mechanism. So the set you finish when you want to quit isn't just physical training. It's installing something in your nervous system that shows up Monday morning when leadership gets uncomfortable.

When discomfort arrives — in a workout, a conversation, a decision — do you treat it as a signal to stop, or as the actual point where the training begins?
