So, I finally realized that it's better for me if I have a couple of stories going on at the same time. I get really excited about a story and then halfway through I loe my excitment about the story (since I know how it's going to end) and therefore I update once every month.
Having more stories it means that once I get stuck with one story, I'll move to the next and therefore I won't get bored with the story. I know that it sounds (and is) crazy, but it works for me. The last week I made more progress in my stories going from story to story than I did with one story the whole month.
And now I know why Patterson writes books so fast!
