You can tell it was written in a month...

Agh please help.
Just started my editing again after doing a few pages and then taking a two-week break. I'm about 80 pages in and I'm just fixing major problems first. The weird thing is that my novel is good. The characters, plot, scenes etc still grab me and make me want to read on.
But MAN is it badly written!
I have basically resorted to dashes and semi-colons for everything that I couldn't be bothered to do properly. I'm fixing every single 'could not' into 'couldn't' and cursing myself for using that to boost my wordcount. I've used 'glanced' 'chuckled' 'smiled' and 'tapped' about fifteen times on every page...
And I wanted to self-publish THIS?!
*facedesk*

Before you self publish it would probably be good to get a critique group, or a professional editor if you're willing to pay for one. They'll be able to help you iron out all the technical problems.

I've had the same problem. I find a word that I like and use it to describe everything. I end up having meandering 7 times in one page. I now have to go through my novel and change the words a bit, put in a bit of variety. I also find myself rewriting whole paragraphs in the process.

Man, what a great problem to have! Sounds to me like your story has got a gorgeous face, sparkling personality, terrific smarts, a body to kill for, and the most god-awful ugly dress ever!

Seriously though, don't despair - it is a heck of a chore to go back and clean up every last one of those sentences, and no mistake, but it sounds to me like it is worth every bit of your time to do that. That what you felt before was not blind arrogance, but the self-knowledge and confidence that are ESSENTIAL for getting through this whole endeavor. So, you know... have faith, persevere, and get back to work!
