I started out watching that guy and still do. I like some of the stuff he does, his inventory organization method, and his method of research on eBay. I'm sure lots of people do it that way but that is where I learned it (Sort by highest dollar sold item, make note of the brands, rinse and repeat...). He went all in with an office space as well. I think he probably knows more than he lets on. He's been doing this for too long.
