What's your story about? Tell me. Lay it all on the line here. There are no wrong answers in brainstorming.
Oh, you want to make a WW2 drama about paratroopers behind enemy lines in occupied France, but also it's a zombie movie? (Overlord, coming soon)
You want to do a sequel/soft-reboot to a problematic-yet-beloved Robin Williams vehicle with a new cast and vastly different premise? (Jumanji: Welcome to the Jungle, one of The Rock's highest grossing movies)
You want to make a horror movie, but it's set in a predominately sci-fi-distopian world, and the monsters react to sound, and most of the movie is told through American Sign Language? (The Quiet Place, 4th-highest grossing horror film of all time)
The point is, there aren't really any "bad ideas" in storytelling. There are bad movies and bad books, to be sure. Sometimes it comes down to the language or the skill of the storyteller, sometimes it's the subject matter and the timing, and sometimes it's just a bad angle from which to tell the story. But you could take any pile of garbage, give it to a talented writer, and watch magic happen.
All of this is to say: Don't give up on your ideas.
Whatever you're working on, see it through. There is nothing wrong with the idea. Maybe you need a new angle, or a new character, or a new car-chase/alien love-making scene. But the idea is sound. Stick to the idea.
And write. Always be write.
Now, without further ado, here's T.J. Berry.
