Can you remember what you were like when you were a kid? How different or the same are you now? Did you turn out the way your parents wanted you to or the way you thought you would? What makes you, YOU? Did you inherit your personality from your parents, or did your surroundings shape you, or was your personality cast before the age of five by the satisfaction or denial of your basic needs and impulses? Yet again it could be that your behavior is determined mostly by your present perception of the world. These theories all have a hand in explaining our personalities and how we can change to become better people–but none of them says it all.
