A new story idea every single day.
Ideas can be shit, detailed, loose, tight, scenario-based, character-based, or could just be a single line of dialogue which might later unfurl itself into a glorious tendril of butt-tickling wonder-magic … or something.
Stole this concept from @ryanklindsay.

Bad superhero/supervillain idea.
A man with the gifts of catnip. Cats cannot resist him. Every morning he looks out his window to see hordes of cats outside his house. He wakes to find cats sleeping on his bed. Might make for a pretty funny villain actually.
