Many people wonder about the personalities of others that how they are same or different from each other. Most of them also want to know how personality works in day to day life. Personality psychology concerns what our personalities are, how they work, and what they can mean to our own and others' futures. The discipline of personality psychology helps answer some of these questions. If such questions interest by the people, then people may want to learn more. In the characterizing, the statement of Gordon Allport, Hall and Lindzey (1957) opined personality as the essence of human being. It is the sum total of ways in which an individual reacts to and interacts with others. Factors that determine personality are both heredity, or genetic, and environmentally determined. Researchers have found that genetics accounts for about fifty percent of personality variation and more than thirty percent in occupational and leisure interests. Specific dimensions of personality include shyness, aggression, submissiveness, laziness, loyalty, and timidity. These are collectively known as personality traits. Traits are believed to be important in employee selection, matching people to jobs, and in guiding career development decisions. In an organized review of the relationship between personality traits and suicide risk, Brezo et al. (2006) revealed neuroticism and extraversion to be the most consistently replicated characteristics to be associated with suicide-related behaviours. Specifically, higher neuroticism was related to suicidal ideation, suicide attempts, and completed suicide, while extraversion was found to be a resilience factor for suicidality.
