How to make my own writing more emphatic

I feel as though my writing is already clear, but I may be wrong. If I am, then to make my writing more clear to my audience, I may need to put the most important ideas at the end of the sentences.(How to write English) If I put the main points in the beginning that will be helpful to the reader and it will keep them interested in my writing. I should keep the end short as in not adding new information to my conclusion. Also, I could have more authority within my writing, which will cause the reader to believe, or at least feel that I know what I am talking about, and allow then to want to read on. These things would help me to make my writing more emphatic, if not already.
