I am so great.

You might laugh.
When I write an essay, I feel I am so great and what I am writing is fairly interesting. In many cases it turns out that my essays need to more effort or fine structure to be great. Actually mines are basically horrible.
In my academic carer in Japan, basically I have not required to write essays usually fill-in examinations. I am so not used to writing essay and still need to practice.
Anyway I am happy and that is important.

In the Introduction of English writing, what is most important things are told such as what the writer want or what aimed to.
In Japanese writing, it should be the end. Japanese people can be shocked if what people want is told at the very first because it is too direct and straight.
In Japanese writing system, people can not see what is told until the end.
