It’ easy to use certain words and phrases over and over again. So, when you’re done writing a scene, take advantage of your writing software’s “find” function to see how often words appear in your prose. Now go through and cut the ones you can or re-write the sentences to eliminate the repetitions.
In compelling drama, bad things happen to the characters; but ending scene after scene on a dark note can exhaust readers. Go back through your manuscript and make sure the negative doesn’t overshadow the positive. Strive for a healthy balanced mixture of both to keep your readers turning the pages.
Before you start writing your next scene, review what each character, not just the POV character, was doing before that scene started. Even if you don’t write those details down, knowing where each character starts off will inform your writing.
Think about the last book you set down before you reached the end. Perhaps the faults that bother you the most are the ones that hit too close to home. With that in mind, revisit that book and see if you can find where you lost interest. Then compare it to your own manuscript to see if you are having similar issues.
Pay attention to your environment when you’re writing and fill it with things that make you happy. If you like sunshine, write by a window or outside when the weather permits as long as the birds and squirrels don’t distract you too much.
