Sometimes these notes make more sense than others when I find them later, because why on earth would I check and organize a thing like that daily? Madness, I say! Sometimes when I go back to them, I can't quite read at least one key word, because it's smudged or ripped or gotten something on it (ew).
Other times, it becomes clear, and I'm like "Oh hell yes, self, why didn't we start working on this sooner? It's great!"
And still other times, it's a great idea but I have no idea where I was going with it (I've got this problem with files on my computer as well, as I've discussed).
Then, once I finally get to writing it, I need to decide if it's a short story or something longer. I typically start short, actually; my novel writing bug, after the high school fantasy novel debacle, didn't really start until after college. Oh, I started a novel in college, but don't worry, that one probably isn't worth reading either.
(and no, I haven't seen this season of Supernatural, so please no spoilers or we can't be friends.)
