The easiest way to learn scales and modes on guitar

I made a video showing my scales and modes e-book. It's by far the easiest way to learn them. And I stand by that. I've known this since 1991, and never saw this taught in any guitar books, so I finally made this e-book. Enjoy, and any feedback is appreciated.
