i am an introvert. My temperament is MELANCHOLIC so my characteristics are Introvert, loner, great thinker, genius-prone, very artistic and creative, often found alone in thought, perfectionist, slow-paced, great understanding of tasks and systems, a critical and challenging mind, and seeing both the pitfalls and the end results of a project undertaken. Extremely moody, suffer from “black” depressions, reject people, set standards neither they nor anyone else can meet, develop habits that are very hard to break, have suicidal tendencies, low self-esteem and are pessimistic.
