Any text, be it a thesis, abstract, article, story, or essay, should have a clear structure. Even a notebook entry, the most nuclear "sketchbook," has its own structure. Let alone an essay. What distinguishes an essay from many other student papers is "pay me to do your homework reviews”. Alas, we all know: the more freedom, the more responsibility. Getting this very freedom, you have to think over the structure of the future essay yourself. The structure largely depends on the goals, form, type, and scope of the work. A narrative essay will start with the introduction, an essay-illustration essay with one or several theses. An essay of the "causal analysis" type will have to line up in accordance with the laws of logic. And in no other way. The structure can simply be thought through. But it's better to take a sheet of paper and sketch an approximate plan. The plan is the "skeleton" of the text, on which you will later build up the "flesh. Any text needs a plan, essays need it in the first place.
