What does it mean that the environment shapes attention?

Physical and digital environments either support or undermine your focus.

Example: You sit down to write a report. Your desk has yesterday's mail, three coffee cups, and a phone face-up showing notifications. Your browser has 34 tabs open. Before you type a single word, your visual cortex is already running a competition between every object in view — each one pulling neural resources away from the report. You haven't failed at focus. Your environment failed you before you started.

Try this: Run an environment audit right now. Sit at your primary workspace and count: (1) the number of objects within arm's reach that are unrelated to your current work, (2) the number of open browser tabs, (3) the number of visible notification badges on your screen. Write these three numbers down. Then remove or close half of each. Work for 30 minutes and note any difference in how quickly you settle into focus.
