Matured !! ??..

I was talking to my friend other day... and She thinks a LOT most of the times(yep, a Philosopher - very few people know!) :-)..
During the conversation, suddenly she mentioned that...I should get matured now, thinking of talking less, behave in a matured way and this n that....
  Now, she is a kind person who can talk non-stop, makes fun and can make anybody smile! She cares for people and lends her hand for unknown people in need!!...does lot of crazy things for fun, never hurting others..
  There is a general notion that, being Sophisticated is like being Matured! - UK style of life.. I feel that is the most BORING life anyone can lead!!... That makes the world feel that everything should be systematic, perfect and mechanical!.. no surprises or deviation from actual path!!... These things are inducted through education and very less space for creativity...People are forced to take a path, a safer way. Very few people come out of that jinx to achieve the bigger things.
  Normally people prefer safer way...sometime even without realizing what they are getting in to.. According to me, making the world joy to live, is a Matured behavior.
hmmmm.... some people get joy in being sophisticated too... they r not wrong either ;-)....
What do u say ? or think??;-)
