Maturity

Maturity comes as we grow up but what do I really mean by growing up isn't just growing older. We grow up when we go through different experiences in life and we learn from these experiences. Age isn't proportional to it but we can't say age doesn't make a difference because chances are an old man would've went through a lot more in life than a kid in his teenage years.

However, there is no certainty in maturity with age because some people may not have much impacting experiences and some may not learn from their past experiences. On the other hand, there may be kids exposed to life changing experiences at a young age forcing them to grow up early.

A matured grown man may sometimes behave like an immature kid when things aren't serious. Every man has a boy inside but that doesn't mean they're any less mature in their thinking. A matured person knows when they can't behave like an immature kid but that doesn't stop them from behaving like one when they can.

People mature through experience, not age.
