A tendency to be impatient is considered a major personality flaw. People who suffer from severe impatience are often considered to be arrogant, insensitive, and overbearing. Impatience can cause a person to cut others off mid-sentence and to make what appear to be uninformed, quick judgements.
Impatience can lead the impatient person to snap at others in response to questions or requests.
Impatience is considered to be a career stopper for many major corporations. Impatient people are not considered to be good managers or leaders for a company. Many factors can lead a person down the road to impatience. One of the biggest causes is stress. The more stress a person feels, the more likely they will be to react impatiently to additional requests for time.
