How many years till a person's personality changes?

How many years does it take for a person's personality to change, even if it's just a little bit? Like for example, a shy 14 year old boy who likes to play video games and acts immature... How many years would it take for him to become more mature, or at least get other hobbies or something?How many years till a person's personality changes?

You are changing all the time.



As for becoming something else, that will require effort. Will not happen on its own.
It has nothing to do with years or even time for that matter. It has to do with experiences and a changing state of mind. Although time is needed for anything to occur, it could take 10 years for someones personality to change, or it could take 2 seconds, where the individual realises or experiences something hence changing personality wise; changing the way that they view things, personal values etc.
It is said a personality is formed permanently by the time someone is about 7. It takes a major life event to change any personality (that's different from a person's preferences, enjoyments, hobbies, etc).
I don't think it would take him years. I think when he gets to the point in his life when he wants to socialize and date girls he will change. Some people play video games their who lives and they still have families and jobs and raise children. You can take up new hobbies at any point in life and socializing just takes practice. He needs to go to football games or church groups or join clubs where other people are. He has to practice talking to people and having conversations and just get out and meet people. It doesn't take years to do that, just practice.
