It is important to remember not to get too carried away when writing the essay. At the end of the day it is still a graded piece of work and will need to be written well. Spilling all of your views onto the page does not necessarily mean you'll get a good grade. You will need to back up your opinion with facts, and write it in a clear and concise way. A persuasive essay can be a pleasure to write if you have properly planned it, have good reasons for your argument, and include an introduction, body of the text and finally a conclusion.
