Thanks to script writing templates that have made this task pretty much easier. Characters always want something. The fear of making mistakes is what stops you from producing any output. But if you are just starting and that you only know one kind of genre, do not attempt at writing a whole new one because it will either require you ten years of research about it or that you will only end up feeling frustrated because for sure, you will not be able to finish one with an outcome that is satisfying.
With these templates you can add ultimate emotions to your story without much efforts. You can also see Writing Proposal Template. This can also be done in quite simple ways without disturbing the overall sequence of the template.
And do not just focus on making your main characters want something; also share some of the spotlights on the supporting characters. You may have been inspired by all those movies and TV shows that you have watched when you were young. If you will be able to complete a lot of work and that you would keep on writing without really worrying about unnecessary things, you will become better and better with your craft.
Stuck in a rut? If possible, get a copy of your favorite TV show or film. Not feeling inspired at all?
Your script will become more interesting if your audience would get to know the characters of the story as the central theme and message of the story through their actions.
