As writers we can literally draw inspiration from anything we see around us. The entire world is a possibility. For example, right now do the following things:
1) Turn on your television.
2) Mute it.
3) Pause it (if you have the technology)
--or just remember what you see when you look at it right ---
Whatever you see on your television screen right now at this very moment is your writing prompt for today.
You can extend it in any way you see fit. For example, if a Red Lobster commercial is frozen on your screen, you can write about the people who are gathered for a seafood dinner, you can write about the lobster, or you can write about the people who caught the lobster in New England or wherever they may be.
