I think I matured quite early, but what that does mean is I have moments of complete immaturity. When I come home, I don't want to be an actor. I just want to be a kid. I barely even know what money is.
Immaturity is the incapacity to use one's intelligence without the guidance of another.
From an evolutionary perspective children are, literally, designed to learn. Childhood is a special period of protected immaturity. It gives the young breathing time to master the things they will need to know in order to survive as adults.
For many, immaturity is an ideal, not a defect.
I am neither bitter nor cynical but I do wish there was less immaturity in political thinking.
