A common problem with many conclusions is that they simply restate the thesis and summarize what’s already been said. This doesn’t give your readers a compelling reason to read the conclusion -- they already know what it’s going to say. Instead, try to take your reader to the “next level” in your conclusion, or provide some further sophistication to your original ideas. There is usually no need to clog up the ending of your essay with quotes and analysis — that should have been what you were doing in your main paragraphs. The conclusion is the place where you tie everything together for your readers, not where you introduce new information. Don't use too many high-flying, two-dollar words in your conclusion. You want it to be readable and relatable, not rigid and boring. It’s much better to have clear, concise language than a meandering sentence stuffed with overlong words. Also, don't use "Firstly," "Secondly," "Thirdly," etc. to make/finish your points. Make it clear what you're saying and how many points you're making. Now is not the time to introduce new ideas or content. That takes the focus off your original argument and could confuse readers. Don’t jumble things up — relay simply where your essay has led and state what you have come to think after conducting the necessary analysis. The conclusion is not the time to nitpick with a small theme in your essay. In fact, it's the time to step back and focus on the big picture. Make sure your essay focuses on the heart of the essay, not one strand of hair. These words are not advanced ways to start a transition.
