Performance means how you deal with problems if they occur despite your preparation and prevention steps. Performance may make the difference between whether your problem remains an incon­venience, or whether it degenerates into a full­ fledged emergency. Performance means taking the correct action calmly and decisively, even though you may only have a few seconds to act and decide.

When you encounter a potentially serious problem - whether your own problem or someone else's - do what you‘ve been taught since your open Water Scuba Diver course: First, stop what you’re doing . Second, breathe normally . This helps calm you and clear your thinking. Third, think, of the most direct, simple way to overcome or correct the problem.
