I heard someone say the other day on the TV that " You can't learn how to be an adult. It is something that just happens to you."

I'm not sure if this is true. I do not think that there is a picture perfect mold on how to grow up. I think that it's an individual story for each and ever one of us. I even believe that some people never truly grow up, not in the sense that they stay childish. But in the sense that they do not make the personal realizations that they would need to. They do not expand and excel their minds and their subjective&objective views on oneself as a person.

In a nutshell growing up is to improve yourself as a person until you reach a certain level where you are viewed as an adult. Really the most significant difference between a child and an adult is that the adult has the ability to further view herself or himself from a more objective perspective and improve ones flaws. Therefor, if someone does not come to the realizations necessary and do not improve ones skill to view oneself from a more objective perspective, you never truly are able to grow up. Achieving this, is in my opinion, a matter of challenging yourself and to truly step out of your own comfort zone.
