Whatever you're working on, be it a novel, a short story, an epic poem, whatever... the best thing you can do is finish it. Even if you think it sucks. Finish it. Even if a new idea seizes your attention. Finish it. Nothing happened for me as a novelist until I actually finished the first draft of my first novel. And yes, a lot of it sucked, but that's what the revision process is for. You can't revise what you haven't finished.
