Write the scene you have to get through now.

Here's some advice I wrote to myself this evening (1500 words!) regarding something that I face over and over with books: Write the scene you have to get through. Don't skip it if you know it needs to be there, just write it. Write it badly if you have to, write it short, write it in bullets and take the bullets out so it looks like paragraphs, write it in dialogue, write it in verse. Write the scene you have to get through and get through it; otherwise you just get stuck at that scene, and you'll come back to the next session and there it will be, waiting and you still don't want to write it. Write the scene you have to get through, and then get on to the next scene you do want to write. Write the scene you have to get through now.
