Self-Loathing to Avoid Self-Editing?

COMPENDIUM manuscript (sorry, didn't have a dinosaur for perspective, but yes, that is a blue canary in an outlet by a light switch in the background)

Behold!

To the right is the first draft manuscript of COMPENDIUM in physical form. It does not look nearly as intimidating as Brandon Sanderson's manuscript for Words of Radiance (best title for a book ever by the way), pictured directly below it. Mine only clocks in at 425 pages in this first draft, where as Mr. Sanderson's final manuscript for Words of Radiance was over 2,000 manuscript pages. Every time I feel intimidated by the re-write process, I have to tell myself that if Brandon Sanderson can rewrite a 2,000 page manuscript multiple times to prepare it for publication, I should be able to suck it up and make it through 425 without any complaining.
