Maturity. when did you achieve it?
By your own definition and standards, when did you feel like you've matured overall? When did you finally feel like you've reached a peak of life knowledge that was usable to you subsequently (without being too late)?
When did you feel that you're in control of your overall life and know what to expect from your future self or where you can take that self in the future? When did you reach a reasonable level of understanding of friendships, relationships, of your place in society, of your position relative to different types of people? When did you feel like you've stopped making the mistakes of early youth, like moving in circles and repeating big mistakes?
Of course maturing never ends. But I'm talking about passing through certain thresholds that were meaningful to you. What are/were the times & moments when you felt that you fruitfully could use an amount of past life experiences that piled up over the years? Please feel free to share as much of your life story as you like.
I'm 24. Based on past moments, I try to anticipate future situations and begin dealing with them right now.
