You can write a draft of ideas you have for an essay, making sure that all ideas are presented, and you can make a chart of how you want something to be presented, i.e. what will be in the introduction, what will be in the body and what will be in the conclusion. You can also plan out how you want the reader to see it. Sometimes in films they show something happening and then say "48 hours earlier" or something. It gives the reader an idea that you actually thought about how you want the story to be told. When you organize writing it's always important to have an open mind about what you're talking about. You can't have a narrow topic that you can't talk a lot about, you need ideas first.
