|I truly need one of these!|
I ascertain the reasoning behind why it takes this long to write a book on a few factors. One, I try to go by a writing schedule due to being the only one who drives in my home. I also am careful and random about how I go about scheduling a writing day, and what book I am going to work on that day. I try not to get burnout, as well. I normally write two or three days a week. This does not include when I do finish a rough draft and spend unlimited time on rewrites and changes.
Sometimes it works out for me and other times it doesn't. Sometimes I end up with withdrawal, like an addict and yes, I can be a total bitch. Then I can write an incredible chapter and all is well again.
Instead of a caffeine fix, it's my writer's fix.
