There are some pretty dramatic simplifications in here. For example, I did not talk about beta readers or perspective readers. For me, after the main revision is done, I send the book to a half-dozen or so people who have things in common with my characters that I don't. Race, gender, nationality, age, socio-economic status, education, sexual orientation, etc. That's one of my favorite parts of the process and gets spread out over a number of months.
