Screenwriting : What happens in my screenplay? by Mario Rossi

In the end here's the question. You've just finished to outline, writing your script and you ask yourself: what happens in my screenplay? Is my story interesting enough to deserve someone's time? I stumbled upon this scene of "Adaptation." where Brian Cox's character replies to Charlie Kaufman: https://www.youtube.com/watch?v=JHVqxD8PNq8 (the real Kaufman had a writer's block when hired for this film) I'm fully involved in each story I write, so I think sometimes I fail to understand how another would feel it (the big dilemma). How do you manage this?
