Are you aware of the big picture? Or are you allowing yourself to get tunnel visioned on one specific item? In watching Air Crash Investigation, I have learned that there have been a number of accidents contributed to crew members on a flight getting hyper-focused on a single event and loosing the big picture of what was happening to the airplane itself and how it was flying.
So how does this relate to Public Safety Tidbits?? In Firefighting you must be aware of the big picture, what is happening around you. But at the same time you cannot allow certain outside distractions to distract you from the task at hand. It is a balancing act of knowing which distractions must be heeded and dealt with and which should be (essentially) ignored or pushed to the back of the mind.
