When Has One Matured?

One has matured when they choose to do what they do for themselves apart from social influences.
The mature are not performing for acceptance, but because of principle, they do what they do.
What they do, is what they believe in. It is their passion.
The mature understand themselves and know what principles they will die for, but don't assume that everyone else will have these same ultimate concerns, but will use their life to further the ends of their commitment of value.
