I don't know about the other writers out there, but anytime I have a new idea, whether or not it's for a current project of mine, I write it down, and I write until I run out of fuel for that idea and I draw a blank and then I just leave it.
Despite them just being random idea flows that sit in and ferment in my head for a few days until I write them all down at 1am for a couple hours, some of them I actually really like.
But I'm going to leave it up to Wattpad. I'm going to post whatever one eighth - spun story I have and if it gets enough votes and likes and whatever, at some point later on I'll come back to writing it. If nobody likes it, then I'll know it isn't worth it lol.
