I can’t avoid them, either. Usually these are major emotional turning points in the story. I think the reason I dread them and put them off is that I don’t think I can pull the transition off successfully. Which is rather like an out-of-shape person not wanting to run a mile because they’re not an athlete.
I’m not going to get good at writing emotional turning points by ignoring them.
Steven Pressfield wrote a good post about how you have to be your own mentor sometimes. Hold your feet to the fire and question whether the story is the best it can be. I would go further and state that even if the story isn’t as good as it could be, you have to try and write it anyway. It’s not going to improve sitting in the back of your mind. You have to get it out on the page first.
