To keep your writing interesting, sentences should vary in length and rhythm. Change up your word choices and eliminate redundancies. If you feel like you’re using certain words and phrases too much, you probably are. Do a quick search in your word processing software to find out.
Don’t be afraid to expand your vocabulary, and remember that the thesaurus gives words ofsimilar meaning. Not every word it gives you will be interchangeable. If you are not sure about the nuances behind a word’s meaning, look it up in the dictionary before you use it.
