Being simple in explanations, it can be said that a good thesis statement is a “door” to your essay and as it is impossible to enter the room without the door, the same situation may happen with the essay. A well-crafted thesis statement allows the reader to plunge into your essay better, to understand the main idea of the essay, as well as to focus attention on the main details.
To create a clear thesis is a hard task for many students, but they need to cope with it because the quality of the paper directly depends on the quality of the thesis statement.
Moreover, a well-designed thesis statement is not only a guide for the reader, but it is also a guide for the writer. It is similar to a guiding star for your essay. Sometimes a writer may get lost in own thoughts and ideas, and a thesis statement is a way to find the right direction for the future discussion.
