If I really love my WIP, it's hard to finish and leave it. Of course, it's a damned good feeling if it's ready, but it's hard to leave that world what you love. Sometimes even hard to leave a chapter behind. For me every chapter is a unique travel into the world of fantasy. But as always, as one dream is fulfilled, another one comes.
Although there is a character what I really like and developed her very well. I used to use her in other of my works too on different ways, keeping her major traits, reshaping her here and there, but the essence remains, sometimes even her name remains the same. She is my main MC.
I've got about 10% to go, and I'm really bummed out about ending it.
For me 5% to go, and it's already hard as I look ahead, because I love to shape this world, figuring out the details, the conflicts and shaping everything in it. Even if I know it's not over at the end, but it will be hard to leave this world.
For me the hardest to look back to the already finished works, when they're already produced and published. I always ask from myself; what should I do different in them now? But as they produced, or published, unfortunately they cannot be changed.
