Yes, but before it is written to learn a little about this form of written expression. Experts agree in saying that it is a literary composition and its purpose is to present an author’s ideas about a topic in a way, almost always, very specific. Sometimes it is short and presents an informal style, thereby acquiring some difference with other forms of exposure. From the explanation above can infer that there are two main protagonists in the task of writing an essay: the topic and the author. Well, in this genre the author has total freedom to address the topic from their own point of view, according to their knowledge, the way in which sees the world, their scale of values, and in general his training as a person dedicated to see the world from their own perspective.
But be careful: when someone has formed its opinion on an issue must defend it and the way to do so is based on arguments. So there the writer has the second most important task after the choice of the theme and is finding arguments to support the position that he assumes. Let’s go party and stop us in the choice of the theme. The issue is not as easy as it seems at first. To find out if a topic is suitable must meet at least the following requirements: which interests you as an author that has an audience also interested in reading about this topic have the possibility of obtaining information relating to the matter that you can assume a sincere, strong and defensible position. Once made the choice of subject should soak up better about it.
Therefore, it is necessary to do some research to complement the knowledge you already had when you chose. You cannot dismiss any source or over-dimensioned the virtues of others. Everything should be in proportion.
