Composed? Nervous?

Composure is a reflection of the ability of the person to control self. High on this trait indicates an ability to remain in control even under pressure. It measures mainly the capacity of a candidate to resist stress. Nervous people rest less well and are accordingly less productive, both mentally and physically.

People extremely high on this trait want to control everything and everybody and are perceived as "bossy". People low on this trait cannot relax and are often tired due to the energy output required to maintain what control they can. These people often have difficulty sleeping and of course, sitting still.
