People that have grown up (le adults) try to stress the importance of one day finally leaving your childhood.
Good for them.
Never being able to let the innocence go is the same as a man spending his whole life trying to find a way not to die.
Just relax and let it happen. Becoming an adult is like entering into a different world. It doesn’t matter how screwed up you were as a kid; now you can do whatever the hell you want! It’s a world where anything is possible. Sure it’s a world that probably sucks, but at least you can make it suck on your terms.
And who knows, it might be a world that’s magical.
It doesn’t matter. After all, the mystery is what makes it special.
