Descriptive writing is a unique form of creative writing whereby you describe an object, emotion, situation, person, etc… You are forced to create a written account of something by way of artistic freedom.
When writing a descriptive essay on the Enneagram personality types, you want to describe your topic in such clear a fashion that the reader walks away with a clearly formed impression in their mind which matches the one in yours.
Writing should function as a focused expression of your studies and your thoughts. As your writing skills are honed, your perceptions and your critical analyses and creative skills will improve too. Writing in this sense is essentially the development of your ideas. Your objective here is to convince your reader that you have sufficiently supported the concept you developed. You must maintain tight organization and sufficient control over your writing. To do this, you need to have a central idea which is your thesis, with several paragraphs which grow systematically from this thesis in support of it, and all of the information you include needs to contribute the understanding the reader has of your thesis. In order words:
Now, for the descriptive essay, you have a bit more flexibility as to the flow or organization of your work, but it should nonetheless serve some purpose for the reader. You want to ensure that your descriptions are each categorized in a separate paragraph with proper transitions in between them so that the reader can easily move from one area of your work to the next.
When you are writing, it is important to consider the reader of your essay. You want to take into consideration who it is you are writing for beyond just your professor. Sure, you want to get a good grade from them, but you might also share this piece of writing with other classmates or friends. Your classmates, for example, may not have the same input as you did on the same piece of work. You could write on the same topic, or a similar one, but you might each take something different from the work and in that you can share with one another your thoughts (check out the topics on personality types prepared for you). You should remember that as you make references to different works or sources, you should tell the audience something they do not already know in lieu of just regurgitating a plot summary or a biography and telling them things they already know (the article about facts may help you to gather information or find the right references for your paper). So remember that even if your entire class has been asked to describe the same topic, you have a great deal of flexibility within that and can let your creativity fly.
