There is nothing more tiresome for a reader, than seeing the same words over and over in the same paragraph. A thesaurus and a synonym finder should be a writer’s right hand. Read your work out loud to hear your errors or repetition of the same words. Avoid overusing the word, it without an explanation as to who, it is referring to. Break up any monotonies. Long paragraphs exhaust the eyes. Break them up to make it more appealing to the reader. Think visually as you write. Use all five senses to make your story come alive for your reader.
