I struggled for almost two years to get out a suitable plot that I felt comfortable with pursuing. Over the course of the time that I was trying to work out the kinks in my plot, I started a variety of drafts--where I could write page-upon-page of detail and action effortlessly. The writing, of course, didn't go anywhere but it as easy. Now that I've started trying to write under a plot where I have some direction. It seems I can't go anywhere with my writing. It's as if I can't propel my story forward. I have this solid plot with an ending, however vague, i mind but I can't move my ideas along as I used to. It's rather vexing because it's not like I'm lacking in skill. I could do it before! Any advice?
