Focus on one thing.

What is the single focus of your...
...sentence?
...paragraph?
...act?
...story?
Too often, writers try to cram in too much. Instead, they should cut out the excess or break it into separate ideas.

If you are struggling to make something work, then simplify. Ask: What is its focus?

PS - This doesn’t mean you can’t have over one idea, but first, get good at focusing on the one before you make it harder on yourself to add more.
