I used to be an INFP.
According to MyPersonality.Info, “INFJs, making up an estimated 1% of all people, are the most rare type (males even more so). They are introspective, caring, sensitive, gentle and complex people that strive for peace and derive satisfaction from helping others. INFJs are highly intuitive, empathetic and dedicated listeners. These traits tend to act as a “tell me what’s wrong” sign on their forehead, hence the nicknames Confidant, Counselor or Empath. INFJs are intensely private and deeply committed to their beliefs.”
