Mr. Suave has the right idea.
It IS a lot of motivational stuff, but it IS necessary. A lot of people who need to read the DJ Bible are AFC's or people fresh out of bad break-ups. Or just regular new members. So, the things that are in there are needed, I think.
People who have been here for years or already have solid game don't really need to read the Fifteen Steps, nor do they need to read most of the beginners material. But there's a lot of good information in there beside the motivational sections.
I've read probably 70-80% of it. It's quality stuff. Most of it isn't my type of game, per say, but it's all useful, depending on the situation.
