Introduction to infp:
Mediation personalities are usually quiet, open and imaginative, and they take a caring and creative approach to everything they do.
Although they seem quiet or humble, mediators (INFP) have an inner life full of energy and passion. They are creative and imaginative, and are willing to lose themselves in daydreams and make up stories and dialogues in their minds. These characters are famous for their sensitivity-mediators can have deep emotional reactions to music, art, nature and people around them.
Idealists and considerate mediators long for deep and affectionate relationships and feel obligated to help others. However, because this personality type only accounts for a small part of the population, mediators may sometimes feel lonely or invisible, wandering in a world that does not seem to appreciate the characteristics that make them unique.
