I get some important thing when writing an essay from last ARW class and some videos.
One important thing is to write the body first, and introduction and conclusion last. Introduction and conclusion have roles of summarizing and paraphrasing, so writing them last is very reasonable.
And another important thing is to make an environment proper for writing essay, and do not too wary about content at the stage of the draft. Making appropriate environment means not only a place, but also time. If we are rushed to completing it, we cannot keep calm, so starting early is important. Besides, when we write a draft, we have to write just as we think without hesitation.
I think firstly concentrate the task and write it through in any case, and then, improve on it later is good order.
