growing up isnt the problem. Its societies preconceived notions of what growing up entails.
my fav quote in that regard:
“To be concerned about being grown up, to admire the grownup because it is grown up, to blush at the suspicion of being childish; these things are the marks of childhood and adolescence…but to carry on into …early adulthood a concern about being adult is really a mark of arrested development. When I was 10 I read fairy tales in secret and would have been ashamed if I had been found doing so now that i am fifty I read them openly. When I became a adult I put away childish things; including the fear of childishness and the desire to be very grown up.”
