Every human is different and has a different personality. Personality is the sum total of ways in which an individual reacts and interacts with others or may be defined as the deeply ingrained and relatively enduring patterns of thought, feeling and behavior. In fact, when one refers to personality, it generally implies to all what is unique about an individual, the characteristics that makes one stand out in a crowd. Generally, we categorize people according to the different types of personalities but personality is developed through the influence of the right or the left brain. The influence of right or left brain varies from person to person and splits people into multiple personalities. That is why everyone has different behavior. We agree and accept that each individual is unique, but what makes one unique is attributable to one’s personality. If we take identical twins, even though they may look alike but their behavior and personality are different from each other. Therefore, we cannot label personalities and we must deal with everyone as an individual case study.
Every person has two aspects of personality, Internal and External personality. Internal Personality is our inner self and External Personality is our outer self, which actually is a manifestation of the internal personality. If we examine people deeply, we are able to understand their thinking and psychology. That means our thinking is reflected through our personality. The way our thinking, our thinking can change our personality too. What we think and believe is reflected through our personality. So, if we believe that we are confident then we would be confident and start behaving that way without any training and just by believing in it. Therefore understanding human personality is equally important as understanding human psychology.
