What is the most frustrating part about being a writer? I don't know about other writers, but for me its discovering a fabulous idea that I start writing on, and then part way into the story the idea fizzles, or I lose interest- So much for that fabulous idea. It gets tossed on that dusty shelf where all stories usually never get a second glance. After awhile, looking at the cluttered shelf can get more than a little depressing and I wonder, "Why can't I finish anything? Why can't I find a story I really want to write?"
Answer... Because I haven't spent enough time developing any idea to the point where I can really know it to feel it inside and out, up and down, and all the way through to the deepest core of the idea.
