This is an excellent way to dip your toes into screenwriting or playwriting, develop your storytelling abilities, and create a tangible piece of work that could potentially be filmed or performed. It hones your ability to convey a lot with a little.
Start by brainstorming a simple concept or an interesting 'what if' scenario. Research basic screenplay formatting (e.g., using free online tools or templates). Outline your scene's beginning, middle, and end, then focus on writing sharp dialogue and evocative action lines. Don't overthink, just get the story down.
A computer with a word processor or free screenwriting software (like Celtx or WriterDuet), an internet connection for research, and a quiet space to focus.
