Motivation

I've been writing and rewriting the same story, going on three years off and on. And because of that fact, I'm finding it boring and lacking motivation to finish it, even though my goal is to do so by the end of the year.  Any advice to somehow say, "I know it's boring to me cause I've been writing the same thing forever, but I want to finish it by December 31st" and actually do so?

Hello fellow writers

I always wanted to see what a blog is like and what the big deal is, so I figured I'd start one for those who like writing. If you have advice, suggestions, or anything regarding writing to your fellow writers, please feel free to post them on here.
