You should take a step back if you find yourself looking blankly at your page, unable to make the connection between the old thought and the new notion you wish to walk your readers through. When in doubt, sketch down a rough plan. If you prefer to use an overview template on your word document rather than writing one on paper, create an overview that contains your thesis statement as well as the primary elements you intend to use to support your thesis statement. Once you've created an outline, you can start moving the parts about. When you have explored your thoughts further, you may find that the sequence in which you began writing the essay does not make logical sense. Moving things around may make it easier to transition between various paragraphs, which is something you should try.
