A good essay is beneficial and really matters to your studies. Like and appreciate what you write, but accept criticism. You may not know it, but the missing piece in an excellent essay could be the writer himself believing that it is one.
Writing an essay might be an easy task; but writing a good essay is certainly not. It is more or less like making that perfect breakfast for your Mom as a token of appreciation for all that she has done for you for so many years. You need to remember the essential ingredients that would go together to make a perfect meal. Similarly, you have to put all the components together and then develop the right kind of style to ensure the quality of the essay. This is just as you would need a large dollop of love to make the meal just right!

Well-articulated descriptions, arguments or ideas stringed together in a meaningful flow which converges into a sensible conclusion would be a good essay, in my opinion.
