The real wisdom here isn't simply that focus requires discipline—it's that distraction isn't a neutral force you can ignore. Goleman understood what neuroscience now confirms: attention is a finite resource, and every moment you spend scrolling or half-listening is literally weakening your capacity for deep work. A programmer who checks Slack every three minutes doesn't just lose time; she retrains her brain to expect constant interruption, making sustained concentration feel almost painful by comparison. The metaphor of starving versus feeding suggests we're not fighting distractions so much as choosing which habits we're cultivating in ourselves.
