Thesis Topic — Stick with it
When you are writing your essay, you should already know what the idea of it should be (whether you want to write it or not). You should write down on paper when you plan to complete your essay, where your research will come from, and make sure you list out every point you need to make. Everything will be organized. Don’t worry about your thesis topic. When the body and possibly the conclusion of your essay is written, you can read everything over. From your overall essay, you should be able to come up with your thesis. There’s is no point in worrying about the thesis when you haven’t even written your essay because you are liable to change things up!
