Who are your inspirations?
Stories grow from random details. We say all the time, “that would make a cool story” or “that would make a cool first line.” Save those thoughts and build on them. You don’t need inspiration for a full story right away. It just needs to start you thinking.
Write down great lines when you hear them. I have a “Great Lines” file that has all the awesome lines I’ve heard or thought of but don’t know what to do with. Snippets of dialog, a bit of description, whatever it is, save it, because that line could spark something greater one day. Or be the perfect piece for a problem you’re struggling to work out.
Sometimes you have to take a step back from what you know to find what you need. I still use that today when I’m stuck on a plot. I forget about what I “know” has to happen and think about what could happen. And then the ideas come.”
