You believed in it. You wrote draft after draft. You pitched it, queried it, and entered it in contests. And nothing.
At some point, belief becomes stubbornness. The industry isn't rejecting you; it's rejecting this specific project at this specific time. And that's okay. Some projects will never be made. But that doesn't mean they were wasted. A great unproduced script is still a great sample. It still proves you can write. It still opens doors, just not the door you originally aimed for.
The danger is putting all your eggs in one basket. One script. One idea. One dream project. If that basket breaks, you're starting from zero.
So ask yourself honestly: Is this project moving forward, or am I just moving in circles?
Your answer determines what comes next.
