I am 21 years old and I am an MBA student. After 2 years I will enter corporate life. But everyone (parents, sibling, friends, and girls) said that I am an immature person. My behavior is like a child.
Even I proposed a girl; she also said that I am not matured, if I look like a matured she will enter in a relationship with me.
I am very much worried and depressed about this problem. How can I recover from this problem and behave like a matured?
Please help me with some bullet points tips and tell me is my behavior normal or not?
