3 non-negotiables to being a better screenwriter:
1.) Watch movies and TV.
2.) Read screenplays.
3.) Write
But do so with intention.
- Don't just watch, break down the movie's structure, too. See the story's 30k foot view.
- Don't just read. Observe yourself. See where you stumble, what you like, what you don't like, what keeps you engaged. Learn.
- Read FEWER classic screenplays; favor NEWER scripts and recently sold specs.
You don't have to write every day. But write enough that your mind stays in writer-mode and you observe the world as a storyteller.
