Ok, so keep in mind that I work a full time+ job (almost 50 hours a week). Writing is a part time thing for me and between work and family, getting good writing time rarely happens.
That said, I'm 26,155 words into my 90,000 word manuscript (29% done) and I'm realizing that I just started the real story of the book about 2000 words ago. That means that I will probably have to go back through those 26,155 words and cut probably a good 20,000 of them which will put me all the way down to 6% done. It's a little disheartening and I'm over here looking at my outline and asking it why it has abandoned me like this.
My plan of attack. I'm going to wallow in self pity for a little bit, then I'm going to revisit my outline to make sure there's enough substantial story moving forward to hit the 90,000 word mark without the beginning quarter of the book (it's a sequel of a book that was over 89,000 and I want to keep the word count consistent). Once I'm confident of the story, I'm going to keep plowing forward until it's done. Then I'm going to hack and slash the beginning to bloody bits in the rewrite.
Once the book is done, I'll take the time to mourn the loss of those words (and time).
