Every writer, I think, has the habit of using two or three words way too many times. For me, it is “but,” “really,” and “just.” I have been fortunate to realize this and either avoid them or take them out when I don’t avoid them. But, they really are just unnecessary.
Just like starting a sentence using “and” or “then” either separately or together. It is rare these words are ever needed like this. If a writer thinks they are needed to introduce the sentence, they should rewrite the sentence.
I could explain this more, but I try to avoid the word “because,” because things should be explained without saying, “Here’s the explanation.”
I try to not start too many sentences with “The.” Many sentences do not need to be addressed that formally. The introduction of people, events, or other incidents should already be there waiting to take action.
Finally, each paragraph should not begin with the same word. At least, not more than twice in a row. Paragraphs should be unlike their past and future selves.
This is all about different word choices. Use a diverse culture of words to be inconsistent. That is the story of creative writing. Writers write a story with a plot in mind and it is the use of word variety that makes it readable.
P.S. I ended my book without the performance. I wrote the chapter and it looked like it was screaming to get it out of there. It fit in perfectly as the introduction into the second book that I was trying to avoid writing.
