A lot of novelists who never complete a manuscript and remain unpublished go by the old reliable excuse that time is so hard to come by. Here’s a little revelation for you: time is always hard to come by, even for published authors.
The biggest difference between being published and not being published is finishing projects. That’s it. That’s all. Whether its a phenphedrine review for a health magazine, a short story for Ellery Queen or a novel for the fantasy section… no one is willing to publish an unfinished manuscript.
Sure, even a finished manuscript can be bad and avoid publication… but finding the time to finish a project vastly improves its odds for reaching published status.
