How to write a conclusion
An effective conclusion is created by following these steps:
Restate the thesis: An effective conclusion brings the reader back to the main point, reminding the reader of the purpose of the essay. However, avoid repeating the thesis verbatim. Paraphrase your argument slightly while still preserving the primary point.
Reiterate your supporting points: Aside from restating your thesis, you should also reiterate the points that you made to support it throughout the paper. But instead of simply repeating the paper's arguments, summarize the ideas.
Make a connection between your opening and closing statements: It's often effective to return to the introduction's themes, giving the reader a strong sense of conclusion. You can accomplish this by using similar concepts, returning to an original scenario or by including the same imagery.
Provide some insight: Your conclusion should leave the reader with a solution, an insight, questions for further study or a call to action. What are the implications of your argument? Why should anyone care? You'll want to answer these types of questions here and leave your audience with something to think about.
