The actual writing phase of your essay can be as painful or painless as you want it to be and it all depends on the amount of time you’ve got between the moment you start writing and the time the paper is due. Your thesis statement will be the nucleus of your paper. Make sure you have a strong enough thesis statement for your essay to ride on. This will help to make your essay as a whole strong and will result in a powerful closing statement. If the weight of your essay is great and everything has been addressed, the pace is even, and so on, there will be little pressure to nail your closing statement.
Another tip is to simply do the introduction—which will focus on your thesis statement—and your closing first. You’re already aware of what the body of your essay will include, so you can write a closing that covers the essay as well as sell your point. You’ve essentially tackled the two parts of the writing stage that will have you revising for a while. The body of the essay—which contains the facts and so on to support your point—will be much easier to take on as a result.
