But, is good enough good enough?
I've since changed my critiquing style. Nowadays when I review, I try not to let any sentence slip by me, no matter how inconspicuous it tries to be. Lines that are not wrong and not great could probably still be revised. Why? Because no one wants to read a book that's just good enough. We want to be consistently impressed. We want every sentence to be a gem that plays an interesting role in your story.
So, check it out the next time you're reviewing your work or someone else's. See how many sentences fall into the "not bad, not great" category. At some point, everyone here is going to be able to write a competent story. It's not the major elements that will separate the greats from the less-thans. It's the little differences, the seemingly trivial decisions.
Note: I really wasn't planning to do any self-promotion today, but I just found out that Opium Magazine is doing something incredibly cool. They've printed a nine word short story on the cover of their next issue that will be revealed one word at a time every hundred years over the next millenium! Check it out.
