It is counter productive to write an abstract or a title before the paper is completed and edited. We discover as we write. Do not put yourself into a box by writing an abstract and then refusing to deviate from it. Do not try to fit the content of original research into a predesigned format or formula. A formula is designed to contain what has been done previously.
Some people work most productively by writing at length rather than by following an outline.
If you produce a lot of text, see what's important, then refine, and shorten. The table of contents is not intended to provide the reader with numbering but to provide an outline of the structure of the article. See if each section heading relates to the material actually in that section. Look at whether section headings extend from or develop the idea expressed in the title of the paper. Do not use a passive voice if you want to continue the discussion.
