Extraverted and spontaneous, or balanced and reserved: these are the ways people identify others around them every day. These personality indicators may seem easy to distinguish; However, sometimes, finding your personality type can be difficult. In the early 1900s, a Swedish psychologist named Carl Jung introduced the idea of ​​categorizing personalities into identifiable types (Boeree). By investigating the subconscious, Jung was able to classify personality types that have certain characteristics in common. This became known as typology (Boeree; TheFreeDictionary.com). Several years later, Katherine Briggs and her daughter, Isabel Briggs-Myers, took Jung's typology to the next level. Together they separated the traits grouped into 16 types (Boeree). They soon created a test in which a person could determine their personality type. The test creates combinations of traits to easily identify a person's personality as one of 16 types. These types include combinations of the following categories: Extraverted/Introverted, Sensing/Intuitive, Feeling/Thinking, and Sensing/Judging (Boeree). Many personality types may have similar qualities, but each type denotes a unique individual. The first of the categories is one of the best known: extrovert and introvert. An extroverted person is said to focus on the world around him. An introverted person tends to focus on the inner self (MBTI Basics). At some point, every person acts introverted and every person acts extroverted. All people need solitude, a time to think and refocus. They also need to socialize with others (extroversion). However, most people tend to lean more towards one trait or the other.
