Many people find it useful to make a brief outline or list of topics to be covered in a piece of writing before they start. The more complex your topic, the more you will probably need to do this. There are valid ways of using outlines, but usually not in the earliest stages of a project. Before you begin drafting, try making no more than a list of the items you plan to include in a tentative order of inclusion. Any more rigid plan, like a formal and detailed outline, will block you from having some of the ideas which might otherwise come to you while you write.
Writing is generative .
The spontaneous ideas which come up as you write early drafts are likely to be at least more original than the ones you come up with jn an early outline. Later in the writing process, when you are polishing your ideas, an outline can be more useful.
