The ability to regulate external distractions and internal impulses, sustain attention on a chosen target, and maintain performance on cognitively demanding tasks over time.
Focus draws on three attention networks: alerting, orienting, and executive control. It goes beyond simply sitting still. You're filtering out distracting stimuli, reducing task-switching costs, and working toward flow states where challenge and skill are balanced (Csikszentmihalyi, 1990). In our always-connected world, attention has become increasingly scarce, yet deliberate training can expand anyone's concentration capacity from minutes to hours.
Notifications pull you away the moment they appear. You try to juggle several tasks at once, yet none reach completion. You check your phone out of habit rather than necessity, often without realizing it. At this stage, the idea that focus is a trainable skill is brand new. You haven't catalogued your distraction triggers, and you have no environmental controls in place.
What Comes Next
If you've checked off most of this list, you're ready to enter the Distraction Awareness stage, activating what Posner calls your alerting network to notice scattered attention in real time and practice single-task focus.
