@Kevin:

This may be 100% bad advice depending on your writing method, but –

Skip the chapter. You can come back later. The fact that you’re writing is more important than the next chronological event in the story. Don’t break that flow. If you find something you can’t bring yourself to write, move on. We live in a wonderful digital age where you can edit and revise on the fly; go to the next scene and come back when you have a greater idea of the whole of the story so you can stitch the scenes together. Write the middle, write the ending, write something you don’t think will even fit in the finished work. Sometimes writing a scene that’s not plot-relevant, that takes place outside of the timeline of the story or in an aside or whatever can give a greater understanding of your characters, your locations, the history, the directions things will take.

Save it as a separate file and let it plant those seeds in your brain. If you end up with somethign you can incorporate later on, you can cut and paste then fill in the blanks.

Just write. Keep writing. If you can’t write the chapter maybe you don’t have a good idea yet of what you want out of that scene. Figuring out just how far your block extends by trying to write something else can give you insight on what it is that’s not working. Maybe you just haven’t figured out how a transition needs to hit its beats. Maybe the whole direction is wrong, unnatural or just no good. Maybe you have a better story that your brain wants to be working on instead. Learn to trust that instinct and you can only improve as a writer.
