Scan the whole pool, not just the loud end. Trouble doesn’t always splash.

Attention drifts towards whatever is making noise, which is almost always where nothing is wrong. Quiet corners are where a problem can grow without interrupting anybody, so a deliberate sweep of the whole area beats following your interest. This is a trained habit rather than a natural one, because your eyes have to be sent somewhere they are not pulled. Coverage, not focus, is the job.

Give yourself a route this week in whatever you are responsible for, and follow it even when nothing seems to need you. Check the quiet end first. Apply the same sweep to your friends and see who you have not heard from.
