If you're ever stuck trying to write an essay, one of the best tricks you can use is to find essay writing examples. The old chestnut "the best way to learn how to write is to read" didn't gain its cliche status for nothing; reading reorients you to the perspective of reader, making you a more mindful writer.
Your essay writing samples can be friends' essays, essays published in books, or just essays you find online. It is important to make sure that any essay writing examples you use are from quality sources, otherwise they might serve as poor examples on which to base your own work.
Once you have your hands on one or many samples, you can use them to give yourself a crash-course in essay writing. Look at your essay writing samples. How are they formatted? Notice the structure of the writing sample. Does it have an identifiable beginning, middle, and end?
Also try and pay attention to the way the author has organized his or her ideas into a cohesive argument. If the essay involves an emotional appeal, identify what strategies the author used to get a reaction out of you. Think about what kind of language is being used and the effect it has on you, as a reader, and how you might manipulate language to your benefit when you are writing your own essay.
Finally, decide whether or not you think the essay is any good. Is the essay's point well made? Are there things you would change? If so, what? It's important to remember that you're using essay writing examples as just that-examples. Copying someone else's work without their permission and passing it off as your own is never a good idea, but if used responsibly essay writing samples can help a great deal if you are having a rough time with your essay.
