I learned things better to know when constructing an essay from some videos.
First, the claim I make should be somewhat controversial, and then it must be supported by reliable evidences. If the claim of the essay is not controversial, there is no meaning of the entire text, because essay is written for persuading others.
I believe this point is very important because controversial or unfamiliar claims are enjoyable and worthwhile to argue.
My topic of the essay concerns food, particularly negative side of food.
I think this subject is worthwhile to argue because most people do not so much think about them, although food is most relevant issue to us.
But searching evidence is more difficult than I thought, especially searching statistical evidences is so laborious. Fortunately I still have time to consider about claims, so I want to search reliable evidences first, and then decide the argument of each paragraph.
