Conversely, sources of despair are negative emotional triggers, and it is reinforced by a negative environment (Bereczki 2343). Despair can be self-created through own imagination or perception of the world as hostile. Previous frustrations or mistreatments can influence those thoughts of hopelessness. Listening to negative comments from others also fosters despair. This explains why leaders must often maintain a positive attitude during a crisis to influence hope over despair. The lack of an adequate and good support system such as family and friends or professionals can influence hopelessness. Listening to negative and despairing words or critiques can sour attitudes and eventually leads to despair.
