How is that buzzword so huge now? Does no one using it realize that the word "focus" by itself... conveys nothing! At least 20 different ways that I could see "focus" being interpreted, most of those conflicting with each other. I suppose that the advice giver is allowed to retroactively choose which definition of "focus" that they actually meant at the time they gave that advice.
