Tip on finishing a good one is to always consider that the script that you do finish that someone can read is going to be much better than the script that you have in your head. And, again, I stress that you have to finish what you start. I mean, there are times when you will start something and it doesn't pan out and you feel like you just have to just let even see it through. But that's the case just start something else, smaller, maybe a short film script. And go ahead and finish it and see it through to the end. Because you have to see something that you can complete something because it's a lot better to have something tangible.
Just reading the invisible script that no one else can read being stuck in your head
