Some people can be especially neurotic or nervous by nature, living out their lives in a state of excessive worry. These obsessive concerns may either be global or amazingly minor in scope. Such a person is often said to be a worry wart, also rendered as worrywart or worry-wart in some literary references. A worry wart's fears are generally viewed by others as irrational or completely out of proportion to the actual situation.
A worry wart in an office environment, for example, may spend most of his or her time fretting over getting laid off or fired. While the actual chances of a worry wart actually becoming unemployed may be remote at best, a neurotic employee often seeks out advice from co-workers on how to handle his or her inevitable dismissal. Others may worry excessively about job performance or customer complaints or minor conflicts with their superiors.
