I typically start an essay ,with try to have your first sentence catch the reader. like if I was doing an essay on the book the great Gatsby I would start off saying something completely different than the book itself. I would say "life is a struggle". then after the first sentence I would give I would get into why I said it was and how that one sentence relates to the book and why I said it, its easy and simple plus teachers eat that stuff up.
State you a thesis statement to start the paragraph off. Then just pose a question related to the subject and then answer the question, state the interesting facts about it. After, that write 3-5 paragraphs, after you found the thesis and question statement and have written you introductory paragraph, write your conclusion, stick to the 3rd Person , and then revise your work .
