This is an opinion question that only you can answer.
Step-by-step explanation:
Think of something that you did that made you feel older and more mature. Maybe you walked to school by yourself. Maybe you did taxes. Whatever it was, it made you feel more like an adult and less like a child.
If you walked to school by yourself, then the lesson you would have learned would to be more independent and do some things on your own. These experiences that make us more mature are necessary to grow up. Everyone has at least one of these.
