everyone has different personality...but, i think most people are scared to be who they are, esp. people from collectivist society like nepal's…. where people act upon how the society wants them to act. So, most people seem to be the same. Whereas, in individualist society, people are appreciated for having their unique ideas and thoughts so that they can flourish in becoming what they really are. There are different categorizations of personality and even the traditional horoscope has divided the personalities into 12 different types. Psychologically, some people sense more, some perceive more, some feel more and people think more, yet they posses all the capabilities in different amounts and that’s what makes an individual unique. Yet, there are people who suffer from personality disorder (again different types) because of some kind of abuse or trauma during their childhood.
