I have writing ADD

BIG TIME. I am working on Dean's story, I promise, but geeeeeez...there's this other story that I cannot stop thinking about and it's driving me CRAZY, so I started writing it as well. I will finish Dean's first, of course, but I had to get the other one down. I feel like I'm making improvement with Dean's though, so that's good news. It's not like I don't want to write his, I want to finish his story more than you want to read it, TRUST ME. It is tough though. It's tough to go back to characters once you've left them behind for too long, especially Dean, especially that series where so many things are interconnected so I have to second guess timelines, etc. My goal is to have it finished by the end of the month (not published, just finished). Can I do this? I hope so :).
