Even with a good career and all the "adult milestones" I don't feel like an actual adult. I feel like I'm pretending to know what I'm doing. Anyone else experience this?
My answer is still the same as this question was asked last time. I still feel no different than my teenage self until I meet some actual teenagers, and and there is nothing that makes me feel more like an adult than when I realize they are just kids, immature and wide-eyed, and the me of now is actually nothing like the teenage me I still think I am.
Being an adult means having grown-up responsibilities, you can no longer be the selfish, carefree child you used to be when there are people depending on you in this cruel, cynical world. Yet in spite of all this, you don't have to give it all up, there should still be times where you can take a break from being an adult, and with the life experiences you didn't have before, rediscover that sense of wonder, hope, and sincerity that you thought you've lost in a brand new light.
