2) Reading through what I’ve done already to get back into the story and characters
What I need to do is just start writing.
My best strategy is to start with one tiny bit. A paragraph. A sentence. (Yes, I've had days where all I've written is a sentence. It was a darn good sentence, too). It's the same way I tackled my revisions. Even though it seems like a snail-like process, writing a small amount every day eventually amounts to something. I'm hoping it will start a snowball effect where I just can't not write.
Do you have any good tips for getting back into the writing flow?
