Why is writing a good conclusion so important? Well, take the example of your favorite detective series. What is the one thing you remember about the episode at the end of the day? For most people it is the way it ended. The same is true for novels, articles, movies, and essays. The part with the most impact should ideally be the conclusion. It is the last attempt on your part to convince your readers that your argument is credible, and to impress them with your writing skills.
