Plotting It All Out

So I've been thinking hard about my story for the past week or so. Whoever said writing is not hard work has obviously not written more than his/her name. But, I'm almost done plotting the whole four-book series out. At least in my head. The truth is, once there's direction, making everything up is pretty fun. 
As for the rewriting itself, I've caught up to where I left off. I've nineteen chapters. I was on chapter ten when I realized that I needed to spread out the action. As one friend gently put it: everything seems to happen at the end. And although I think I do a pretty good job of setting everything up, my main character has to take a couple of more turns before Chapter 12, the point of no return. 
¡Salu!
