perhaps you could explain what you mean by "theory"? That's been mentioned to me before that my book was lacking, and I have to say, I've no idea what it is. lol

Do you mean, stuff like the bouncing ball lesson and the like?

So far, the main driving philosophy behind my first, and also, this book is to do a how-to on actual job work. This is stuff that I literally do every day at work. Ya know?
