There are a few things you should keep in mind when starting a formal paper. First, you want to make sure you have a strong hook. This will help grab the reader's attention and keep them engaged. Second, it is helpful to provide some background information so that your reader has context for your argument. Third, make sure you have a clear thesis statement that outlines what you'll be arguing in the paper. Fourth, map out the structure of your essay so that it is easy for the reader to follow. And finally, don't forget to proofread before you submit!
