EVERNEATH CONTEST. Go enter. Now.
There are times when writing feels like a job. Particularly during the revisions process, I find myself procrastinating, getting distracted, and making every possible excuse not to work. Revisions just aren't that fun for me. There's none of the creative excitement of a first draft, and after multiple read throughs I get bored by my own writing. When you can recite paragraphs without reading them you know you've read a book one too many times.
Sometimes writing is hard work. We persevere. We do it even when it's not fun. But if you ever get to the point where writing is a constant hassle, where you can't bring yourself to sit down and work, something's wrong. Writing should never be awful. Sure, revisions can be tough, but if they're pulling you down it's time to take a break. Work on a new project. Forget writing for a week or two.
Because if you lose the joy of writing, then your stories will come out dull and bland. Always remember what brought you to writing in the first place. Keep that in your mind, that love of storytelling, and you'll be able to get through revisions just fine.
