Writing Theory: Drafting the "Throwaway" Draft

The "Throwaway" Draft is often the first draft, or initial ideas one has for a written piece. Apparently, William Faulkner used the following metaphor for drafting, "Building a barn in a tornado." While I haven't been able to verify if this is an actual quote from Faulkner, the truth it holds is not detracted, and it's very much one I agree with. It essentially harps on writing some interpretation of your ideas for a piece immediately once you have them, for the longer you sit idly on them, the faster they dissipate. But what about the approach to writing the actual "throwaway" or initial draft?
Well, firstly the throwaway draft does not have to be a display of excellent writing or expression by any means. In fact, I find that all of my throwaways are quite atrocious, that is, after all, why they are called "throwaways". Their purpose is solely to put your idea to paper, to facilitate further thought on the idea, help it foster and develop.
John E. Schwiebert provides some excellent tips for throwaway draft writing in Reading and Writing from Literature; Third Edition. While the book primarily focuses on analytical essay writing, I find the advice he provides applicable to many different writing forms.
Here's a short excerpt of a list of tips he provides;

"-Focus yourself by jotting down your working thesis
-Write quickly for a limited time period (twenty to thirty minutes works well)
- Make sure the draft has a beginning and an end, however sketchy
-Do not concern yourself with getting the correct phrasing...as fumbling over these matters will break your train of thought
-Whenever you get stuck and can't think of a word, phrase or, scentence, leave a blank and push on. If you are undecided between two different words or phrases, include both and seperate with a slash... Aim to achieve overall shape for the piece and worry about the details later."- Schwiebert

Good notions to keep in mind while writing initial drafts on projects. The only one I would perhaps dispute is the suggestion of having time limitations. I prefer to simply write and let my thoughts on the subject flow throughout the writing until they come to a halt. This of course causes the necessity of longer review time to determine what parts of the draft shall remain than perhaps a time limited throwaway draft would, but I would advocate it nonetheless.
Regardless, it's important to write a throwaway draft for all of the potential ideas you have a desire to write on, and it's important to write about them asap, without care of how sloppily the draft may be written.
