My biggest problem as a writer is that I always get inspired and then start writing from the middle, in particular scenes or moments which I think will be crucial. Climaxes. These scenes turn out really great, but then afterwards, when I try to go back and fill in the part between the opening and those scenes, it always turns out embarassingly awkward, much worse than my writing usually is. I can never really fix it, so what I end up with is a story that seems like some great writer hired a fourteen year old to fill in the gaps in his idea notebook.
I should clarify that it isn't so much writing the beginning that is my problem- my opening scenes are usually good- but the few pages between the opening and the first 'moment.' I've considered trying to figure out how to just not write those parts, but then it seems like the reader doesn't know the characters well enough for my good scenes to have the right impact.
What do better writers than me do to deal with this?
