I was literally asking the same question I'm just like that, I'm always laughing and acting like a kid n I'm 19... But unless it has had a serious effect on u why would u wanna change tho

I was that boy who usually do only childish thing but later I figure out my problem is not loss of maturity but it is that I want to be liked by everyone so I am that clown to impress them ... So that was my problem so I just stop try to impress people and be myself then it brings huge difference

Try to copy every character of your mom…immediately you will become mature enough.

Think

Love Yourz

Read psychology and philosophy books.
