Seems like its a lot of marketing for desperate guys like me?
I'm embarrassed to admit I bought a few "quick fix" guides before finding DB, not that particular one but they were on sites that looked way too much like that one. It's just a ploy to pay too much for what is basically something that would get a "C" if submitted as a high school weekend essay project. Don't do it, you'll just be angry at how badly you got ripped off.
