A person’s unique personality emerges over time through thought and behavior patterns. Personality development is impacted by genetics, one’s environment, and a variety of variables that set us apart from other persons.  Personality development is the process of developing a set of individual traits within a person that contribute to the overall personality. Personality development matters because it plays an essential role in an individual’s personal and professional life.  Understanding our personality type is essential to understand ourselves, and how we view our environment.
