Writers' Pride

You've just written a chapter that your very proud of. The sentences are lyrical. The action is engaging. It's then you realize that it isn't the direction the story needs to go. But its so good.
Letting it go was one the hardest things I learned to do (and I did a lot of it.) The trick is to not get attached to your writing.
Stephanie Meyer wrote a 700 paged sequel to Twilight called Forever Dawn. She didn't like it so she chucked all 700 pages! (Where does she find time to write 700 pages anyway?)

Sure, be proud of your writing, of what you accomplish. But don't be attached to every word.

If you're not failing every now and again, it's a sign you're not doing anything very innovative.
~Woody Allen
