Center of the Universe

I was young, and I was naive. I lived this little world, in the center of my own universe. I lived a carefree life, doing what I wanted when I wanted. There was no such thing as consequences, or aftermath. None of the usual rules applied to me.
I could only live in such a bliss for so long, though. Everything I knew came crashing down on me like a cosmic explosion, and my little universe disappear and reality appeared. The worst part? It was all my doing.
