To improve the overall appearance of your mini-essays, you can use sub-headings. This will be easier to read the text and understand its general logic.

Pay attention to the volume of essays. It should take no more than seven pages of printed text. Specify the essay topic. The essay should answer only one question. Do focus on trust-style communication with the reader. Let the story is exciting. Avoid complicated sentences and obscure speech.
Try to surprise the reader with pondering some aphoristic saying. Do not use slang in an essay, and reduce frivolous tone. At the same time, do not use fancy phrases, the text should be clear to any reader.
