I absolutely agree! I love writing, but I get this insane idea for like the middle of the story, and I would only be on like chapter four. It gets me frustrated, cause then I want to rush, which makes my story sloppy. So you are really not alone haha.
I do that all the time. I think a lot before I go to sleep, so sometimes, I'll come up with this awesome thing, and I want it to happen right then, but of course you can't do it just yet.
No you are not alone... that happens to me too.. But I also have this bad habbit of starting a story and then not finishing it. :/ But that happens when I start telling myself: no one's reading this so why keep going? Which is why I created an account on mibba.. hey, when you can check out my story When Moonlight Hits...I'm writing this story with some friends and I would really like someone's opinion on how its going so far :D
So you are really not alone haha.
