Have you ever gone back to something you started wring years ago? Maybe it was something you thought would never go anywhere, or maybe it was something with a lot of potential but other events got in the way.
I’ve been looking back over my earlier writing lately, and though I’m not impressed with the quality of the individual sentences, some of the content is decent, if not solid. I’ve started to notice that some of my more recent pieces are actually extensions of older works, as if I’m retelling the same story in a different (better developed) way.
If you’ve been writing for a long time, I’d encourage you to look back over your incomplete projects. Even if they aren’t masterpieces, there’s always something salvageable. You might be surprised.
