Maturity is frequently defined by how you respond to external stressors and internal impulses.

To "just mature" isn't a single event, but a lifelong process of biological development, emotional discipline, and cognitive shifting. While the "brain development stops at 25" idea is common, new research suggests the brain continues refining itself well into your early 30s.

: A core marker is moving from blaming others to accepting consequences for your own actions.
