Had an idea for a really terrible/great story, but can't write it when I've got two ongoing. The struggle is real.
I think the trick is to focus on the reactions and how the spankee and spanker feel about it rather than the actual spanks. Write about how aroused they get. Write about the spreading redness as the spankation leaves marks. How the spankee wiggles, moans, whimpers and begs for release...
Can never tell if I'm writing too much or not enough. Whichever, I am not writing exactly the right amount, or at least not the right stuff.
Word count quotas come to mind when I think of 'quantity' and 'writing' in the same sentence. Obviously, it gets kids to write more, but I'm not sure if it ever really improved someone's quality (or quantity) of life.
I'm know it's probably really bad advice, but if I'm ever in a really bad mood, I look at cute cat videos and after a while I feel better. Change animals as needed if it helps.
I like this site because when I have that problem, I can leave one story for the other writers and focus on the next one.
Have a real banger of an idea for a story, but I don't want to post it because I'll lost interest and don't have time to write it.
You could try dropping it into the Story Ideas forum and hope someone picks it up eventually. Or do you want it done in a particular way you don't trust anyone else with?
I don't think anyone else would go for it, it's...too niche. Considering some of what I've written, that's saying something.
