Procrastination or incubation

I'm in a dilemma, this is that I'm not, or maybe I just cannot, but I must do this first. You know if you give me some time I will.

Am I procrastinating? maybe.

In all seriousness, I am suffering from a dilemma. I have been told that when finishing you first draft of a novel you must move on to some other project. This is to give yourself distance from the characters and plot that has drilled them selves out of you brain for the last twelve months or so. I have done this by writing the start of a new book. I have written the first three chapters and hit a wall, that wall being what comes next. The problem started when I began to revise my first book. All I can see is where I need to take the characters into a second book. I can see the sky. The people and most exciting of all the new characters that are beginning to pop into my head.

Every time I start to work on forth chapter of my new book that is supposed to distance me from this. I write like I'm writing for the second part of my first book. I getting confused so you must be very confused.

My question is do I give in and start on the second book, while revising the first. Or preserver with the forth chapter of my new story?

I'm I just incubating the new story. It did start strong, then I hit the wall. I think it was that I have no idea where the story is going. It's not that I need to know the ending, it's just that I need a goal to aim for. That goal can move change or do what ever it wants. I just need something there to lead me.

Comment always welcome.
