I mainly write scripts but sometimes I don't want to do an outline and feel unprepared to write a scene. I like knowing exactly what's supposed to happen in a scene before I dig in. To avoid stagnation, my methods as to how to keep moving forward vary. One thing that works when I want to feel the story more and get in there more is I choose a different form to write my story. So if for example you are a novelist but are having a hard time with a scene, you could write it out script form, as if it were a movie. Just a scene - not the whole bloody thing. And if you're a script writer, write it out like a short a story. So for example, Episode One is a short story, Episode Two is the second one, and so on. In one screenwriting course before I wrote my script, the teacher had us write the movie trailer. It was a great idea, fun, and I realized I had more of a story than I initially thought. It motivated me and we can all use a little extra motivation.
So go into a new form for a beat just to set fire to your ideas, your characters and you might see your world even more realistically. There's the potential to notice nuances you wouldn't have seen otherwise. Might work for a beat in terms of getting your characters down, your story down, and it could help you get closer to the essence of your idea. And it's fun.
Just a tip. Hope it helps! Good writing to you!
p.s. GO OPRAH! Talk about motivation. Jeez Louise!
