New Beginning

I started my new book today as an idea just popped in my head. Thing is, I started from about the second chapter because I can't think of how to start the damn thing. It's ok though, I know these things work themselves out.
I am not going to tell you what it is about yet, mostly because I myself am not entirely sure. I decided to go into this novel blind, with a few muddy ideas about characters and plot, but nothing concrete. I love writing this way because you never know where the story will take you. Sometimes my characters do things and say things that I just didn't expect. Sometimes I try to resist them, and tell them that this is my story and you are not cooperating, but they usually manage to get their way in the end.
It really makes me wonder if there is something else that controls the story and simply guides our hand as we put it to paper.
I will keep you posted, as I said to a friend today, if this one is a keeper or a throw away.
