I think the majority of us start there.
I can recommend that you practice. It costs a lot, especially at the beginning, but it’s necessary. Explore writing in general, not just on Episode. Read articles and books about writing. There’s a book that’s often recommended to aspiring screenwriters: it’s titled Save the Cat. Maybe check that out? Also, a lot of Episode writers have blogs with great advice, so check those out as well. And of course, watch movies and TV shows and observe how the scenes unfold, how the characters interact, what dialogue works. If you like reading, do the same with books. It is recommended that you follow the Hollywood style on Episode, though, so at least with movies and TV, you got a start.
Be observant, imitate. Let yourself be inspired by the stories you like. Remember that nothing is 100% original, so don’t feel bad about using elements from other things you’ve seen or read out there. Just add your own twist, thus making them your own. Maybe it’s the setting, the mood, or the characters’ backstories. Maybe it’s a combination of these and more. And when you’re ready, maybe write one scene, not necessarily from the beginning of your story. Keep experimenting, dare to “fail,” though it’s not failing, it’s learning. You have a desire to write, so you’ll get there.
I am on the same page as you right now, I think. I struggle a lot with writer’s block. But if you ever need someone to beta test your story, I’d be happy to.
Best of luck! Don’t give up.
