Sometimes, when story telling, it's easy to get caught up in crafting beautiful sentences and creating a flow of ideas. You can lose sight of the bigger picture, or what the story is really about. In those moments, it's worth asking. “What am I actually trying to say?” Try to boil everything down to the simple, underlying concept. Write really basic sentences to reflect that concept, you can always come back and embellish later, if you think that the storyline needs it.
