You know that part in writing when you have a plan mapped out but you're not sure HOW you're going to get there?  When you're partway in the story and writing is kind of like watching the next scene in a movie because you don't know what's going to happen?

That's where I'm at right now.  And it's fun.  Something I haven't felt in a while.  My actual writing feels pretty lame but the story is fun.  I'll have to go back and tinker with wordage later but I'm trying not to overthink it too much and keep myself focused on the story.

This is where I usually start to fade.  Halfway into the manuscript, I freeze.  I know, of course, that the middle is hard.  I've read plenty of blogs/books on that subject; but for me it's more about feeling like my words aren't pretty enough, or the story is not original enough.  I don't want to think that way this time.  I just want to enjoy the process of writing it.  And due to my new resolution, I'm making myself push through.

I seem to always assume others struggle where I do; but that's probably NOT an accurate assessment. ;)  So I'm curious, what's the hardest part of writing a story for you?
